Where in a roller coaster is the gravitational potential energy the most?
At the start.
At the top of the first hill.
At the bottom of the first hill.
At the end of the ride.

i would say at the top of the hill

Explanation:

A cart on a roller coaster has the most gravitational energy when it is at the highest point of the ride.

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.

friction

explanation:

they us to move forward and backwards
