Question

What forces would cause a change in a body's state of motion

Answer 1

Answer:

Explanation:

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.

The action from a force can cause an object to move or speed up (accelerate), to slow down (decelerate), to stop, or to change direction. Since any change in velocity is considered acceleration, it can be said that a force on an object results in the acceleration of an object.

Answer 2

Any external force that acts on a body existing in a state of rest or of motion.

• Force is the product of the mass of a body and its acceleration.
• This means that force is associated with the mass of the object as well as its change in velocity and its change in position with respect to time.
• Friction is a force that acts in the opposite direction of the motion of the body. It acts normal to the surface of the body in cases when the body is at rest.
• Normal force that acts on a body at right angles to it is acted upon by the object that the body is in contact with.
• These forces primarily oppose the state of the body that they are existing in, already.
