What is the difference between the gravitational force of an object and the gravitational force expe

The gravitational force of the body and the gravitational force of the object are the same meaning, and the gravitational force is a force that arises due to the attraction of the earth to the object near the surface, so since it is this benefit, he must have the gravitational force of the object of the instance object and the object of the force, that is, the force that is directed at the attraction of the earth to the object. That is, the gravitational force experienced by the object. These two words are the same for you.

There is no difference.

It's just that the difference between junior high school and high school is the gravity of the object, and it must be clear that it is the force generated by the attraction of the earth to the object, but it does not mean that the attraction of the earth to the object is gravity, because the attraction of the earth to the five bodies, we call it gravitational force, and for the object on the earth, the contribution of gravitational force to it is two and one is around, so that the object circles the center of the earth or the address. Walk in a circular motion. Then this gravitational force creates a small baggage that causes the object to move in a circle, and another component is to make it press against the ground.

Even after leaving the ground, this force will cause him to fall back to the ground. This is the gravitational force of the object.

Regardless of the object's position, it will eventually fall back to the ground if it is subjected to gravity. For example, if a tree branch does not support a bird, the bird will fall back to the ground. If he takes off, then it means using the buoyancy of the air on it, or the lift of the air on it, to overcome the gravitational pull of the earth on it.

If there is no one below the acrobat to support him, then the actor above will inevitably fall back to the ground, and the parachutist will quickly fall back to the ground without the action of the parachute.

Numerically it is the same, but the gravitational force of an object refers to the pressure of the object itself on the earth, while the gravitational force experienced by the object is the force exerted by the outside world on the object.

Gravity 1, gravity refers to the force experienced by an object due to the attraction of the earth, and the force applied by gravity to the object is the earth.

2. The direction of gravity is always straight downward. The point at which gravity acts on an object is called the center of gravity.

3. The magnitude of gravity can be measured with a dynamometer, and the tension or pressure of a stationary or uniform linear moving object on the dynamometer is equal to the magnitude of gravity.

Mass 1, mass is a physical property of an object, is a measure of the quantity of matter, it is a positive scalar quantity. Mass is divided into inertial mass and gravitational mass. Any matter in nature has both inertial and gravitational mass.

2. Mass is the only factor that determines the difficulty of the change of the motion state of an object when it is subjected to force, so mass is a physical quantity that describes the inertia of matter.

3. Mass is one of the basic dimensions in physics, with the symbol m. In the International System of Units, the basic unit of mass is the kilogram, the symbol kg.

The relationship between gravity and mass.

1. The gravity of the object at the same point on the ground is proportional to the mass m of the object, and the calculation formula is: g=mg, g is the proportion coefficient, and the size is about, which is an average value; At the equator g is minimum, g =, and at the poles g is maximum, g =.

2. The mass determined by gravity is called gravitational mass. In fact, people use the weighing method to measure weight, and the relationship between the mass m and the weight w of an object is obtained: w = mg, and g is the gravitational acceleration at a certain point on the earth.

3. Weight and quality are two different concepts. When an object is moved from the Earth to another planet, its mass does not change, but its weight changes.

Gravity: The force that arises due to the attraction of the earth is called gravity.

Measure with a spring scale in the direction straight down.

Mass: The amount of matter contained in an object is called mass.

Measure with a balance. Quality has no direction and does not change.

Magnitically, g = mg (g is gravity, m is mass, g is gravitational acceleration).

The relationship between the magnitude of gravity and mass.

Question 1: What is the force object of gravity, what is the force object The force object of gravity is the earth, and the force object is the object being studied, for example, the gravity of the lead ball studied, the force object is the lead ball, and the gravity of the egg is studied, and the force object is the egg.

Question 2: What is the force on an object due to gravity The force experienced by an object due to the attraction of the earth is called gravity. The object of gravity is the center of the earth.

The direction of gravity is always straight downwards. The gravitational force on the object is proportional to the mass of the object, and the calculation formula is: g=mg, and g is the proportionality factor.

Question 3: What are the properties of pressure and gravity in junior high school physics? What is the difference between a force object and a force object? 20 points The pressure is elastic, the pressed object is the force body, and the other is the force body!

Gravity is a field force (gravitational force), the earth is a force body, and an object is a force body!

FYI! Problem 4: The force on the object due to is called gravity, and the force applied by gravity is always in the direction of gravity The object near the earth is affected by gravity due to the attraction of the earth, and the object that exerts the force is the earth; The direction of gravity is always straight downward; The ratio of the gravitational force experienced by an object to its mass is constant, so the gravitational force is proportional to the mass; So the answer is: the attraction of the earth; Earth; vertically downward; Proportional

Question 5: What is the gravitational force on an object Gravity is a type of gravitational force, specifically the gravitational pull of the earth itself on objects on the earth.

The magnitude of gravity is equal to the physical mass multiplied by the acceleration of gravity, and the direction is vertically downward (that is, tying a heavy object with a rope to make the rope droop naturally, and the direction of the rope is the direction of buoyancy).

Question 6: What is the friction force on the object? Like gravity or external force?

If the object is stationary relative to the contact surface, then the static friction is equal to the component of the resultant force in the direction of the parallel contact surface; If the object is moving relative to the contact surface, then the sliding friction force is equal to the component of the resultant force on the perpendicular contact surface multiplied by the friction factor. Follow-up question: What is the friction factor?

The ratio between the frictional force and the positive pressure when the objects in contact with each other move towards each other. Addendum: What grade are you in?

Question 7: The force experienced by the object due to is called gravity The direction of gravity is always The force experienced by the object near the ground due to the attraction of the earth is called gravity The direction of gravity is always vertical downward, that is, it always points to the center of the earth Therefore, the answer is: the attraction of the earth; vertically downward;

In the approximate case, it can be considered that the object of gravity is the earth, and the object of force is the object on the earth or near the earth's surface. But gravity is not equal to the gravitational force of the earth on the object, and the direction of gravity is always straight downward. The gravitational force exerted on an object is proportional to the mass of the object, and the formula is:

g=mg。Due to the rotation of the earth itself, in addition to the poles, the objects in other places on the ground are together with the earth, around the earth's axis to do approximately uniform circular motion, which requires a centripetal force perpendicular to the earth's axis, this centripetal force can only be provided by the earth's gravitational force on the object, we can decompose the earth's gravitational force on the object into two components, one component f1, the direction points to the earth's axis, and the large and small jujube is equal to the centripetal force required for the object to move around the earth's axis in an approximate uniform circular motion; Another component g is the gravitational force on the object.

Physically: Gravity is the force that causes an object to be subjected to due to the attraction of the earth is called gravity.

Mass refers to the amount of matter that an object contains.

The magnitude of the gravitational force is called the weight.

To sum up, gravity is a force that has a magnitude and direction, and weight only refers to the magnitude of the gravity force.

PS: The weight in life refers to the quality of the physical service.

The relationship between the gravitational force and the mass of an object is directly proportional, and the force experienced by an object due to the attraction of the earth is called gravity. The force of gravity is the center of the earth, and the direction of gravity is always straight downward, and the gravity of the object is proportional to the mass of the object. Comparatively, the formula is:

g=mg, g is the proportionality coefficient, the gravity is about the same, and the gravity changes with the change of latitude, indicating that the gravity of a Weihao Song object with a mass capacity of 1kg refers to Zheng Wei.

Gravity is the mutual attraction between objects and is a fundamental force of nature. According to the law of gravitation, the gravitational force between objects is proportional to their masses and inversely proportional to the square of their distances. As a result, the gravitational interaction between objects with greater masses is stronger.

The effect of gravity on an object is the effect of gravity on an object, for example, it can keep an object still or move, and it can affect the shape of an object. In everyday life, we often use the action of gravity to describe the effect of gravity because it is easier to understand and use. Thus, gravity is a physical force, while gravity action refers to the effect of gravity on an object.

The force exerted on an object due to the attraction of the earth is called gravity. The object of gravity is the center of the earth. The direction of gravity is always straight downwards.

The gravitational force experienced by the object is proportional to the mass of the object, and the calculation formula is: g=mg, g is the proportionality factor, the gravitational force is about, and the gravitational force changes with the change of latitude, indicating that the gravitational force of an object with a mass of 1kg is.

Gravity Mass Gravitational acceleration, g=mg

g (gravity) = m (mass) multiplied by g (gravitational acceleration (
