What does reciprocating motion mean and what is reciprocating motion

The movement that goes back and forth is called reciprocating motion.

Reciprocating motion and uniform linear motion are both linear motions, and their velocity is in a straight line, and they both belong to the type of linear motion.

For the total displacement, the displacement is only related to the initial and final positions, and can and can only be used with the average velocity * time. Generally speaking, average velocity is not used in reciprocating motion.

As for the total distance, because the rate of reciprocating motion varies from time to time, this formula is not suitable for use in most cases.

In general, the total displacement and distance should be related to the period.

Total displacement: first look at the time of motion, subtract n periods until it can not be reduced, calculate the time to which position it will move, and then calculate the distance between this position and the beginning.

Total distance: It is also subtracted n cycles until it cannot be reduced, calculate the distance s1 taken in the remaining time, and the distance s2 made in one cycle, the total distance is s1 + n * s2

Reciprocating motion, unconditionally or conditionally moving back and forth in an area.

The displacement of the reciprocating motion is equal to 0 because it is a positive stroke and a negative stroke. Piston motion is reciprocating motion. Multi-finger mechanical movements repetitive round trip. For example, pendulums, piston movements, etc.

The most famous is that the crankshaft drives the slider for small reciprocating distances; In addition, the distance of the rotating two-way lead screw mechanism for reciprocating motion can be larger. It mainly depends on how much you require the reciprocating motion to be, and there are various conditions, such as whether the rotary power machine can move or not. Multi-finger mechanical movements repetitive round trip.

One form of exercise is repeated.

It has the following two meanings:

1.back and forth; Repeatedly. Example: Reciprocating motion.

2.Dealings. Example: Going back and forth between Beijing and Shanghai.

It's what it means to move back and forth.

This is often the case with physics problems.

The back and forth motion of two sides near a certain position is reciprocating motion.

The displacement of the reciprocating motion is equal to 0 because it is a positive stroke and a negative stroke. Multi-finger mechanical movements repetitive round trip, such as pendulum, piston motion, etc.

The most famous is that the crankshaft drives the slider for reciprocating motion with a small distance; The pure disadvantage is that the distance of the rotating two-way lead screw mechanism for reciprocating motion can be larger. It mainly depends on the amplitude of the reciprocating motion, as well as various conditions, such as the rotary power machine can move to do the Wu family, or it can't move.

Question 1: What does reciprocating motion mean The displacement of reciprocating motion is equal to 0 because it is a positive stroke and a negative stroke.

Piston motion is reciprocating motion.

Question 2: What are the characteristics of reciprocating motion It is a damping motion, and it will eventually stopQuestion 3: What is the difference between reciprocating motion and reciprocating motion that is often talked about in high school physics, thank you!! Reciprocating motion is because motion has a direction.

The round-trip movement does not necessarily have the same path.

Question 4: What is the reciprocating motion The most typical is the piston engine.

Question 5: What kind of motion is called reciprocating motion, and what are the requirements Isn't it repeated motion, returning to the original position after movement, and the displacement is 0, such as piston motion.

Question 6: What are the characteristics of reciprocating motion in 4th grade science Characteristics of reciprocating motion 1, in reciprocating motion, the direction of the movement of the object changes at the turning point 2, take the shout In the reciprocating motion, the magnitude of the movement of the object changes at the turning point 3, in the reciprocating motion, the size and direction of the object's motion change Question 7: How can you win 9 cards of the same suit:

And: 147 258 369

See the same suit and draw.

No! The condition for the simple harmonic vibration of the particle is that the force experienced at any time is proportional to the displacement of the particle from the equilibrium high yard position, and its direction is opposite to the displacement, always pointing to the equilibrium position. And table tennis.

The reciprocating motion up and down is always missing in one direction: vertically downward. So it's not a simple harmonic vibration.

Mechanical vibration is the reciprocating motion of an object or particle near its equilibrium position. You are talking about this movement, the balance position does not exist, right?

The falling reciprocating motion of a ping-pong ball can be used to prove the law of conservation of momentum.

However, since the impact consumes energy, retrospective suspicion does not prove the conservation of energy.

It's not clear what the term is called a sport.

a. The ball moves back and forth at any time, but the force does not meet the conditions of simple harmonic motion, so it is not simple harmonic motion, so A is wrong;

b. The upper end of the light spring is fixed, and the lower end is connected to the heavy object, and when the heavy object vibrates up and down, the resultant force of the heavy object and the displacement of the object relative to the equilibrium position meet f=-kx, which is simple harmonic motion, so b is correct;

c. On the smooth plane, the light spring fixed at one end constitutes the reciprocating motion of the spring oscillator, and this model is the spring oscillator model, which belongs to the simple harmonic motion, so C is correct;

d. The child swings, only when the swing angle is very small, it can be regarded as a simple harmonic movement, so D is wrong;

Therefore, I chose: BC
