A force is a push or pull that causes an object to move, change direction, change speed, or stop. Without a force, an object that is moving will continue to move and an object at rest will remain at rest. ... Not all forces cause motion, however. Some forces, like gravity and friction, resist or work against movement.

Does a force cause motion or a change in motion?

Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity. Remember that acceleration is a change in velocity.

Does force cause yes or no motion?

In such a case, the net force acting on the body is 0 and hence there is no change in the motion of the body. If it was at rest, it will stay at rest and if it was moving, it will continue to move at the same speed.
