Energy Skate Park
Track potential, kinetic, and thermal energy as a skater moves.
Live Values
PE
2940 J
KE
0 J
Thermal
0 J
Height
6.0 m
Formula
PE = mgh, KE = 0.5mv²
At high points potential energy is higher; at low points kinetic energy is higher.
Try this
Reduce friction and observe how the skater moves for longer.
Correct, friction is low and thermal energy grows slowly.
