This question is worth 54 points ! rock falls from a ledge to the ground what energy conversion occurs during this process a potential to kinetic b kinetic to potential c thermal to mechanical d chemical to mechanical

A. potential to kinetic

When the rock was ready to fall off the ledge with energy building up (potential energy), it started falling off the ledge. (kinetic).

Thermal energy comes from heat, generating movement. (No heat in this scenario)

Mechanical energy comes from the sum of kinetic and potential energy in an object that is used to do work. (Like a wrecking ball, not in this case though, because the rock came from stop, to motion, to finish).

Hope this helps :) Brainliest?

the answer is 3.1 his answer is wrong mines is right
