What are 5 energy conversions in a roller coaster?

Answer 1

I only know of two:

1)potential energy to kinetic energy

2)potential energy to gravitational potential energy

Answer 2

1. Potential energy to kinetic energy: at the top of a hill, the coaster has high potential energy which is converted to kinetic energy as it speeds down the hill.
2. Kinetic energy to potential energy: as the coaster climbs up a hill, its kinetic energy decreases and is converted back to potential energy.
3. Mechanical energy to thermal energy: friction between the coaster and the track converts mechanical energy into thermal energy, causing the coaster and track to heat up.
4. Electrical energy to kinetic energy: in a launched coaster, electrical energy is converted to kinetic energy as the coaster accelerates along the track.
5. Potential energy to sound energy: when the coaster goes over bumps or loops, potential energy is converted to sound energy as the coaster vibrates and creates noise.
