what is thermal energy and heat

• a type of kinetic energy. as a substance heats up, the atoms move faster

• a type of potential energy. as a substance heats up, the atoms move faster

• a type of kinetic energy. as a substance cools down, the atoms slow down

• a type of kinetic energy. as a substance heats up, the atoms slow down

what is mechanical energy?

• The combination of both kinetic and potential energy. the energy of an object due to its motion or position.

• a type of kinetic energy for machines
