Question

A roller coaster at an amusement park goes from the top of a tall hill to the bottom. during this time, the roller coaster

Answer 1

There are a couple of things happening while the coaster goes from the top of the hill to the bottom:

• The coaster loses gravitational potential energy.
• The coaster's loss in potential energy becomes its gain in kinetic energy.
• The coaster's gain in kinetic energy causes it to speed up.
• Maybe the coaster is also losing some of its newly gained kinetic energy to friction due to contact between the coaster's internal components and air resistance.
