Which statement is correct? (a) net force causes motion. (b) net force causes change in motion. explain your answer and give an example.

(b) Net force causes change in motion.

Explanation:

There can be a motion even if there is no net force acting on an object.

It can be justified by giving an example:- when object is  moving at constant speed then it has no net force and still is in motion.

If there is a net force acting, then the object will accelerate and this will cause change in motion.

The change in motion can be change in direction of motion, change in speed of motion.

For example when an object is moving in east direction if someone accelerate it this will result in change in motion or change in speed and after some time the net force is applies in the north direction then the object will move in the north direction which proves that the net force also causes change in direction.

We have that for the Question "Which statement is correct? (a) Net force causes motion. (b) Net force causes change in motion. " it can be said that

Option A

From the question we are told

Which statement is correct?

(a) Net force causes motion.

(b) Net force causes change in motion.

Explain your answer and give an example.

Generally

Motion speaks to a change in the position of an object.

Therefore

From the statements is the options the Net force can cause motion and change in the direction of motion.But can not change motion

Hence

Net force causes motion.

Option A
