What are the two main types of energy?
Potential energy is stored energy that is waiting to be released. Kinetic energy is the energy of motion. Both potential and kinetic energy exist in different forms.
Potential and Kinetic Energy
Potential Energy: Energy that is stored and has the potential to do work (e.g. a stretched elastic band). Kinetic Energy: Energy that an object has due to its motion (e.g. a moving car). Energy: The ability to do work, such as producing heat, light or motion.
Concepts:
Potential energy can be converted into kinetic energy. Gravitational potential energy is the energy an object has due to its height. Kinetic energy increases as the speed of an object increases.
Fun facts:
