A roller coaster is at the top of a tall hill and then races down. Describe how its potential and kinetic energy change as it moves downhill?
Its potential energy decreases, while it's kinetic energy increases.
Two objects have the same mass, but one is hotter than the other. Which object generally has more thermal energy, assuming they are made of the same material?
The hotter object generally has more thermal energy.
Two identical bowling balls are held at different heights. Which ball has more gravitational potential energy and why?
The bowling ball held higher has more gravitational potential energy because it is at a greater height.
