Question

Explain why the roller coaster's potential energy is
greater at point 1 than at point 4.

Answer 1

Potential energy is directly related to the height of an object. Point 1 is higher than point 4, so the potential energy is greater at point 1.

Explanation:

Answer 2

The roller coasters potential energy is greater at point 1 because, it's the beginning and the energy hasn't yet been used. When it reaches point 4 the energy is low because it was just moving.

I hope this helps I might be wrong and there was no picture to go along with the problem :)
