Is it the same to find the average rate of instantaneous velocity?

The instantaneous velocity is not the same as the average velocity, the instantaneous velocity has a magnitude and direction, the average velocity is only the magnitude, the second instantaneous velocity is the velocity at a certain moment, and the average velocity is the magnitude of the velocity in a certain period of time. The definition of physics is different, and it makes no sense to say whether the method is the same. Is it possible to say that in some cases the value of the instantaneous velocity is the same as the method of the average velocity, or that they are equal in magnitude?

Velocity: A physical quantity that describes the speed and direction of motion of an object, the rate of change of displacement to time, and a vector quantity.

Average velocity: The ratio of the displacement of a moving object to the time taken in a linear motion with variable speed, vs t (the direction is the direction of displacement).

Instantaneous velocity: The velocity corresponding to a moment (or position) in the direction of motion of the object.

Rate: The magnitude of the instantaneous velocity is the velocity;

Average velocity: The ratio of the distance traveled by the particle to the time, which may not be the same magnitude as the corresponding average velocity.

Average speed = distance time.

Average velocity = displacement time, and the direction is the direction of displacement.

The average rate magnitude and the corresponding average velocity may not be the same.

Instantaneous velocity: The velocity corresponding to a moment (or location) in the direction of that moment (or passing through this position).

The direction in which the object is moving.

Instantaneous rate: The magnitude of the instantaneous velocity is the instantaneous rate;

The average velocity is the average velocity of the object in a period of time, the instantaneous rate is the velocity of the object at this point in time, for example, the velocity of the object in the first second is 5m s, the velocity in the second is 4m s, then, at the first second, the velocity is 5m s, and the average velocity in 2s (5*1+4*1) 2=m seconds.

1) The instantaneous velocity is a vector and the average velocity is a scalar. The average velocity is the average over a period of time and is equal to the bit removal time.

2) The instantaneous velocity is a vector quantity, and the instantaneous velocity is a scalar quantity. Instantaneous velocity is a numerical value at a certain moment on the velocity function.

3) The absolute value of velocity is velocity.

Average velocity is a vector that describes the average speed and direction of motion of an object, and it roughly represents the motion of an object over a period of time.

The average velocity is the ratio of the distance traveled by an object to the time it takes to travel through that distance, and the average velocity cannot be zero for a moving object.

Instantaneous velocity represents the velocity of an object at a certain moment or passing through a certain position, the ratio of the displacement in an infinitely short period of time adjacent to that moment to the time taken to pass through this displacement v= x t. Instantaneous velocity is a vector quantity that has both magnitude and direction. Instantaneous velocity is a quantity in an ideal state.

Instantaneous velocity refers to the velocity of a moving object at a certain moment (or position). In its physical sense, instantaneous velocity refers to the average velocity in the vicinity of a certain moment in a very short period of time. The magnitude of the instantaneous velocity is called the instantaneous rate, or velocity for short.

2. Average rate, instantaneous rate relationship.

Velocity is a physical quantity that indicates how fast or slow an object is moving.

Average velocity refers to the approximate velocity of a particle in motion.

Equal to the bit removed by time.

The average rate is equal to the distance divided by the time.

The difference between displacement and distance is that displacement is a directed segment from the beginning position to the end position. The distance is all the distance you have traveled.

Instantaneous velocity refers to the velocity of a particle at a certain point in time.

Homeopathic rate is the magnitude of instantaneous velocity, also called velocity.

In a uniform linear motion, the instantaneous velocity is equal to the average velocity.

Help me look at this question.

I can't read it**Oh dear, can I type.

What is the motion line of an object that moves in a curvilinear motion?

When an object moves in a curvilinear motion, its motion line is usually curved and no longer straight. The motion lines of curvilinear motion can be curves of various shapes, such as arcs, spirals, etc. During the curvilinear motion, the object will change direction along the curved path, and the tung scrambler has different velocities and accelerations in the same position without slipping.

The motion line of curvilinear motion can be described by the change of displacement of an object with time, and it is usually necessary to use concepts such as centripetal Li spine force and tangential velocity to analyze and explain the characteristics of curvilinear motion. <>

Would the image of the curved motion be a semicircle? It's the kind of coordinate diagram where the ordinate is the distance and the abscissa is the time.

The image of curvilinear motion can be a semicircle, but it depends on the specific motion. If an object is moving in a uniform circular motion, then the relationship between its deficit distance and time can take on a semicircular image. In this case, the ordinate represents the distance of the object, and the abscissa represents the time.

Average Rate = Total Displacement Total Time, Instantaneous Rate = Limit (The amount of displacement change when the time interval approaches zero time interval).

1. The average velocity refers to the ratio of the total displacement to the total time in a period of time, and the instantaneous velocity refers to the instantaneous velocity at a certain moment, that is, the instantaneous velocity of an object at a certain moment. It can be calculated by finding the limit, i.e., gradually shrinking the time interval so that it approaches zero. The average rate is the average velocity over a period of time, whereas the instantaneous rate is the instantaneous velocity of an instant.

2. The average velocity refers to the ratio of the total displacement to the total time over a period of time. It is a measure of the average velocity of an object over a period of time. The average rate can be expressed by the following formula:

Average velocity = total displacement of total time. For example, if the total displacement of an object from the start to the end is 10 meters and the total time is 2 seconds, the average rate is 5 meters and seconds. The average velocity can be used to describe the overall motion of an object over a period of time, but it does not provide specific information about the velocity of an object at a particular moment.

3. Instantaneous velocity refers to the velocity of an object at a specific moment, which can also be understood as instantaneous velocity. Unlike the average rate, the instantaneous rate only focuses on the velocity of an object at a certain instant. It can be calculated by taking the instantaneous displacement of the object at that moment in contrast to the instantaneous time.

The instantaneous rate can be expressed in terms of differentiation, i.e., the velocity is equal to the derivative of the displacement versus time. In physics, instantaneous velocity is an important concept that can be used to describe the specific velocity information of an object at a specific moment.

Usage of average velocity and instantaneous velocity

Average speed of application:

1. In daily life, we often use average speed to describe the speed at which vehicles, people, or other objects are moving. For example, we can say that the average speed of a car is 60 kilometers per hour.

2. In sports competitions, the average speed can be used to evaluate the performance of athletes. For example, in a long-distance race, we can calculate the average speed of the runners to compare their running speed.

Application of instantaneous speed:

1. In physics, instantaneous velocity is the velocity of an object at a certain moment of infiltration. It can be used to calculate the instantaneous acceleration and instantaneous displacement of an object.

2. In the field of engineering and transportation, instantaneous speed can be used to analyze the driving situation of vehicles, such as applications in traffic flow control, vehicle navigation and traffic accident reconstruction.

1. The definition is different: average rate.

is the distance traveled per unit of time (the route traveled); Average.

is the displacement per unit of time (a vector of the first and last positions of a particle during that time).

2. The velocity has only one size, which is a scalar quantity.

In addition to the magnitude of the velocity, there is also a direction, and the direction is the tangent of the trajectory curve at this time.

Direction, is a vector.

3. The average velocity is a vector, and the average velocity is a scalar. Instantaneous speed.

is a vector and the instantaneous rate is a scalar.

4. The average velocity refers to the average over a period of time, which is equal to the time of bit removal. Instantaneous velocity is a numerical value at a certain moment on the velocity function.

5. The absolute value of speed.

It's the rate.

1.The average velocity is a vector and the average velocity is a scalar.

2.Instantaneous velocity is a vector quantity, and instantaneous velocity is a scalar quantity.

3.The average velocity is the average over a period of time and is equal to the bit removal time.

4.Instantaneous velocity is a numerical value at a certain moment on the velocity function.

5.The absolute value of velocity is velocity.

An error will occur.

For example, the average velocity is the ratio of displacement to time, while the average velocity is the ratio of distance to time. And the magnitude of the displacement is usually not equal to the distance.

The magnitude of the displacement is the length of the straight segment between the first and last positions, while the distance is the length of the motion path. The magnitude of the displacement is independent of the path, whereas the distance is related to the path of motion.

The bits are removed with time, which is the average speed. Like velocity, it is also a vector quantity, and its direction is the same as the direction of displacement.

The distance divided by the time is the rate. It is a scalar quantity and has no direction.

The bit is removed by time, and when this time is infinitely close to zero, it is the instantaneous velocity. It is also a vector and is the direction of velocity at a certain moment.

Because the rate itself is an average, the term "average rate" is false.

In the same way, the term "instantaneous rate" is wrong.

Some people say that the "instantaneous rate" is the absolute value of the instantaneous velocity, which indicates the magnitude of the instantaneous velocity. Strictly speaking, we can only say "the magnitude of the instantaneous velocity", not the "instantaneous rate".

1.Instantaneous velocity and instantaneous velocity are physical quantities that describe instantaneous states.

The instantaneous velocity is a vector quantity, and the instantaneous velocity is a scalar quantity (that is, the magnitude of the instantaneous velocity, regardless of direction).

For example, a uniform circular motion is a motion with a constant instantaneous rate, and the magnitude of the instantaneous velocity is constant, and the direction is changing.

2.Average velocity and average velocity are physical quantities that describe the average over a period of time.

The average velocity is removed with bits in time, which is a vector, which has both magnitude and direction.

The average rate is divided by time and is a scalar quantity, only size, no direction.

For example, the average velocity of a week in a uniform circular motion is 0 because the displacement is 0; The average rate is not 0, it is the circumference divided by the period.

3.The difference between average velocity and instantaneous velocity.

The average velocity can only roughly reflect the speed of the object's motion over a period of time, while the instantaneous velocity can accurately reflect the speed of the object's motion at any moment. For example, Liu Xiang's 110m hurdle time is 13 seconds, which is 110m faster than Robles

Time 14 seconds.

Fast, that is, the average speed of Liu Xiang is faster, but it is not certain that the entire 110m Liu Xiang must be the fastest, maybe the first 55m Robles is faster, and then 55m Liu Xiang catches up. That is, the average velocity is a description of the whole, and in order to know the movement at each moment, the instantaneous velocity at each moment must be known.

The average velocity over a short period of time can be seen as the instantaneous velocity at a certain moment.

First, velocity has magnitude and direction. The velocity knows that there is a size, and there is no direction, which is equivalent to the speed in junior high school physics. Velocity alone is generally average velocity, unless instantaneous is added in front, as for what is average and instantaneous, I don't need to say.

Velocity Displacement (straight-line distance between two points) Time, direction is the direction of the line between two points.

Rate Distance (actual elapsed length) Time, no direction.
