# Can the second hill of a roller coaster be higher than the first?

## Can the second hill of a roller coaster be higher than the first?

By conservation of energy, the potential energy will decrease and transform into kinetic energy. When the roller coaster has just passed the first “valley”, it has a lot of kinetic energy, so it can climb up the second “hill”. By conservation of energy, it can climb up to a height equal to that it went down before.

Why do rollercoaster hills get smaller?

In most roller coasters, the hills decrease in height as the train moves along the track. This is necessary because the total energy reservoir built up in the lift hill is gradually lost to friction between the train and the track, as well as between the train and the air.

## Why can’t the third hill of a roller coaster be higher than the first hill?

Each time the roller coaster goes downhill, its gravitational potential energy decreases and its kinetic energy increases. With so little total energy left, the roller coaster can’t have much gravitational potential energy and must be much lower than the top of the first hill.

### Which is better STEP2 or STEP2 extreme roller coaster?

The Extreme Coaster is the better buy, as it will entertain for years – while the smaller roller coaster has almost lost its appeal now, due to being too small and slow to appeal to kids (as opposed to toddlers, who do enjoy it quite a bit).
