1. Energy is the ability to do work.
2. Energy is measured in joules (J).
3. Two main forms of energy are
(i) Potential energy which also known as potential energy.
(ii) Kinetic energy which also known as kinetic energy.
4. Complete the chart below: (No chart provided)
5. Potential energy is the energy that an object possesses due to its position and mass. Work is done when the energy is released. It is stored in the objects that are lifted, stretched, compressed, and raised at a height. The amount of potential energy depends on mass and height from the Earth's surface.
6. Kinetic energy is the energy that an object possesses due to its motion which depends on its mass and velocity.
7. A hot object has thermal energy while light energy is the energy gained from objects that emit light. The sun is the main source of heat and light energy on Earth.
8. Sound energy which travels in waves is produced by vibrating objects. It can only travel through matter but not in a vacuum.
9. Chemical energy is the energy stored in foods, fuels and other chemical substances while electrical energy is the energy produced by the movement of electrons in the form of electric current which is then converted into other forms of energy to do work.
10. Nuclear energy is the energy stored in the nucleus of an atom which is also known as atomic energy. There are two types of nuclear reaction including fission and fusion.
