A eastward force is applied to an eastward moving soccer ball that is already moving at a constant velocity to increase its speed in that direction.
A cart is moving at a constant velocity of 10 m/s [W] when a 0.5 N [downward] force is applied.
The work done by Earth on an arrow as it is fired 200 m straight up into the air.
Earth applies a force on the Moon as the Moon travels one completion rotation in orbit around Earth.
