# Energy Transfer of chairlift

Kennedy111

## Homework Statement

Propose an explanation for the following fact. Include a description of the energy transfers that would take place when the lift starts and stops.

A fully loaded chairlift requires more energy to start then it does to maintain motion.

## The Attempt at a Solution

I thought that perhaps it takes more energy in the beginning because the chairlift has inertia and is resisting the change. You need to apply more energy to get over this initial inertia.

I'm having a hard time including energy transfers...

I know that when the lift starts riders gain gravitational potential energy, which eventually turns into kinetic energy on the way back down the hill..

Thank you !
