Answer 1

The correct option is D

All of the above

If the force is applied in the direction of the motion, it will increase the speed of the moving body. However, if the force is applied in the direction opposite to that of motion, it will decrease the speed or may even bring the moving body to rest. A force can also change the shape of an object.
