What is mechanical energy?
300
In order to make a solid change phase to a liquid, this type of energy must be added.
What is heat energy?
300
This is the force that most commonly gives objects potential mechanical energy.
What is gravity?
300
When a roller coaster is going down a hill, it is converting its potential energy into kinetic energy. However, this force is turning mechanical energy into heat.
