Answer:

There are many reason why something will stop moving. For example, if you throw a ball up into the air it reaches a max where it stops due to both gravity pulling it down and the air resistance that the ball is experiencing.

Another example is if a car is driving on a flat road and the driver takes the foot off the gas the car will come to a stop after some time due to the friction that is being caused by the road. The energy from the tire would get consumed as friction occures between the road and tire where the enegery would be transferred to the road.
