An object exists in a state of rest or in a state of motion. 

When a force is applied on a body at rest, it can start moving. e.g. a stationary football is kicked.

When a force is applied on a body that is in motion, it can also bring it to rest. e.g brakes in a vehicle. 

Similarly, a force can change the direction of a moving body as well as the speed of moving body. e.g. a cricket ball hit with a bat.
