Science Q3

1. ENERGY

2. Energy: Its Form and
Transformation
Major Kinds of Energy
1. Potential Energy
2. Kinetic Energy

3. 1. Potential Energy
• Potential Energy is an
energy that is stored in a n
object at rest.
• Ex: Stretched rubber band

4. 2. Kinetic Energy
• Kinetic Energy is energy in
motion.
• Ex: A ball rolling on the
ground

5. Kinetic and Potential Energy

6. Different Forms of Energy
• 1. Mechanical Energy
• 2. Chemical Energy
• 3. Radiant or Light Energy
• 4. Electrical Energy
• 5. Sound Energy
• 6. Thermal or Heat Energy
• 7. Nuclear Energy

7. 1. MECHANICAL ENERGY
• Mechanical energy is a form of
energy possessed by moving
objects.
• It can either be Kinetic or
Potential Energy.

8. MECHANICAL ENERGY

9. 2. CHEMICAL ENERGY
• Chemical Energy is a type of
energy stored in molecules.
• Food from plants and animals
contain chemical energy.

10. Chemical energy

11. 3. RADIANT OR LIGHT ENERGY
• Radiant or Light Energy is a
form of energy that travels in an
empty space.
• It can be in form of Light,
ultraviolet rays, x-rays and
radiation.

12. Radiant Energy

13. 4. ELECTRICAL ENERGY
• Electrical Energy is produced by
moving Electrons.

14. Electrical Energy
• Static Electricity- is produced when two
different materials are rubbed to each
other.
• Current Electricity- is flowing electricity

15. 5. SOUND ENERGY
• Sound Energy is the energy
produced by vibrating objects.
When objects vibrate, sound is
produced.

16. 6. THERMAL OR HEAT ENERGY
• Thermal Energy is present in
everybody because of the
motion of molecules.

17. 7. NUCLEAR ENERGY
• Nuclear Energy is produced
during Nuclear Fusion and
Nuclear Fission.

18. Nuclear Energy

20. Other Forms of
Energy

21. Geothermal Energy

22. Hydroelectric Energy

23. Wind Energy

24. Magnetic Energy
