Answer:

when a sled is moving, the kinetic energy is changing beacuse of the speed and mass. its cause the sled to move, and changes because you aren't at a constant speed. potential energy changes when you get on. because you are adding more weight causing the gravity to change.

During the high point when the sled is unmoving, there is stored energy (potential energy) and when the sled finally moves downwards, there is motion (kinetic energy).
