## What happens to the gravitational force between two objects when the distance between them is a doubled b halved?

(b) If we halve the distance between two bodies, then the gravitational force becomes four times.

## How does the force of gravitation between two objects change when the distance is reduced to half?

According to the law of gravitation, the force of attraction acting between two bodies is given by, Thus, when the distance between the objects is reduced to half the gravitational force increases by four times the original force.

## Does gravitational force depend on medium?

Answer. Explanation: Gravitational Force does not depend on the medium between the objects. Thus, Gravitational Force is also independent of medium between the objects

## Why is gravitational force independent of medium?

Gravity is unipolar, attractive. So when it goes through a medium, there is no polarizing effect or polarizing forces. Thus the gravitational constant is independent of the intervening medium.

## Does electrostatic force depend on medium?

Gravitational force is always that of attraction while the electrostatic force may be attractive or repulsive depending upon the nature of interacting charges. Gravitational force is unaffected by the intervening medium. The electrostatic force depends on the dielectric constant of the intervening medium

## Is gravitational force conservative?

A conservative force is a force with the property that the total work done in moving a particle between two points is independent of the path taken. Gravitational force is an example of a conservative force, while frictional force is an example of a non-conservative force.

## Is the normal force conservative?

The normal force is non-conservative, and therefore has no associated potential energy. The type of work done by the normal force, however, will depend upon the specific situation: Substantial deformation is a signal that the normal force has done measurable negative work (dissipating mechanical energy) on the system

## Is Work conservative or nonconservative?

If work is done, the force is nonconservative. In other words, a particle located at the same physical location in a closed loop must have the same kinetic energy at all times if it is within a conservative system. This fact is the fundamental definition of a conservative force.

## What exactly is conservative force conserving?

About Transcript. A conservative force exists when the work done by that force on an object is independent of the object’s path. Instead, the work done by a conservative force depends only on the end points of the motion. An example of a conservative force is gravity.

## How do you prove a force is conservative?

Equivalently, a force is conservative if the work it does around any closed path is zero: Wclosed path=∮→Econs⋅d→r=0.

## What is conservative force prove that gravitational force is conservative?

Kinetic energy acquired by the body at the bottom of inclined plane is. Clearly the work done by the gravitational force does not depend on the angle of inclination or path of the falling body. It depends on the initial and final position of the body. This proves that gravitational force is a conservative force

## Does speed depend on mass?

Mass doesn’t affect speed directly. It determines how quickly an object can change speed (accelerate) under the action of a given force. Lighter objects need less time to change speed by a given amount under a given force.

## What is the relationship between mass and speed?

Since mass doesn’t change, when the kinetic energy of an object changes, its speed must be changing. deals with faster-moving objects. The faster an object moves, the more necessary it is to use this theory in order to be accurate. As an object moves faster, its mass increases.

## Why mass does not affect acceleration?

“What are the factors that affect the acceleration due to gravity?” Mass does not affect the acceleration due to gravity in any measurable way. The two quantities are independent of one another. Light objects accelerate more slowly than heavy objects only when forces other than gravity are also at work.

## What happen to the acceleration when there is an increase of mass?

The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.

## When force is fixed does an increase in mass increase or decrease acceleration?

Now explain what it means to say, “Acceleration is inversely proportional to mass.” It means that if force is constant, as mass is increased, acceleration decreases. resistance to changes in motion (also known as INERTIA.) 15.

## What happens to acceleration if mass is doubled?

The acceleration is equal to the net force divided by the mass. If the net force acting on an object doubles, its acceleration is doubled. If the mass is doubled, then acceleration will be halved.

## What is a Newton equal to in terms of mass and acceleration?

1 Newton is equal to 1 kilogram-meter per second squared or 1 N = 1 kg-m/s squared

## What is the difference between mass and force?

The mass of an object is a measure of the object’s inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. The pull of gravity on the earth gives an object a downward acceleration of about 9.8 m/s2.

## How does mass affect impact force?

Heavier objects (objects with more mass) are more difficult to move and stop. Heavier objects (greater mass) resist change more than lighter objects. Example: Pushing a bicycle or a Cadillac, or stopping them once moving. The more massive the object (more inertia) the harder it is to start or stop.

## How do you calculate the force of impact?

F = m * v² / (2 * d) ,

- F is the average impact force,
- m is the mass of an object,
- v is the initial speed of an object,
- d is the distance traveled during collision.

## How is impact load calculated?

To calculate the force of impact, divide kinetic energy by distance

## How can impact force be reduced?

Minimizing Impact Force

- If you jump to the ground from any height, you bend your knees upon impact, extending the time of collision and lessening the impact force.
- A boxer moves away from a punch, extending the time of impact and lessening the force.

## What are 3 factors that determine force of impact?

Speed, weight, and time between impact and stopping all affect force of impact.
