What is another word for potential energy?
Stored energy
The type of energy in action, making something move or change:
Kinetic energy
What type of energy is caused by atoms and molecules moving faster and colliding after being heated up?
Thermal (heat energy)
What are the types of energy that make a torch work?
Chemical energy from the batteries, electrical energy, light energy.
What is the difference between temperature and heat?
Temperature is a measurement of how hot something is (how fast particles are moving, heat is the energy flow, moving from hot to cold
