## Which forces are responsible for motion of an object?

The force responsible for changing the state of motion of objects in all these examples is the force of friction. It is the force of friction between the surface of the ball and the ground that brings the moving ball to rest.

## What produces the movement of an object?

For an object to move, there must be a force. A force is a push or pull that causes an object to move, change direction, change speed, or stop. Not all forces cause motion, however. Some forces, like gravity and friction, resist or work against movement.

## What is the movement of an object?

You can describe the motion of an object by its position, speed, direction, and acceleration. An object is moving if its position relative to a fixed point is changing. Even things that appear to be at rest move.

Sir Isaac Newton

## What is natural state of an object?

Objects do not change motion without unbalanced force. Objects in motion do not always require a force to keep them moving. Objects have two “natural” states of motion, at rest (static equilibrium) and moving at a constant speed and direction (dynamic equilibrium).

## Why do objects stay at rest?

Inertia is the tendency of all objects to resist any change in motion. Inertia causes a moving object to stay in motion at the same velocity (speed and direction) unless a force acts on it to change its speed or direction. It also causes an object at rest to stay at rest.

## Is the normal resting position of an object?

Description. In physics, rest is the state of an object being stationary relative to a particular frame of reference or another object; when the position of a body with respect to its surroundings does not change with time it is said to be “at rest”.

## Do all the bodies have same inertia if not name the factor which determines inertia of the body?

Answer:No, all bodies do not have the same inertia because all the quantity does not have the same quality to strives.
