• Potential Energy (PE)
  
  

• Kinetic Energy (KE)

​Two Main Types of Energy

The ability to MOVE or CHANGE matter in some way.

The ability to do WORK (physics)

SI units - J (Joules)

Science Definition

Thermal energy is the total kinetic (motion) energy of the tiny particles that make up matter. The faster the particles move, the warmer the matter becomes.

• The energy of electric charges

• Can be kinetic

• can be potential

• Energy stored in chemical bonds

• When the bonds are broken the energy is released

• Form of energy that travels through space in waves

• The light we see from the sun

• Cell Phones

• Microwaves

• Radio Waves

• Stored in atoms

• Released during a nuclear reaction

• Fission- Splitting of atoms

• Fusion- Atoms join together

• Nuclear fusion reactions occur continuously in the sun, releasing tremendous amounts of energy

STORED energy

or

Energy that is ready to be released.

​

Potential Energy

Energy that is released

or

Energy in motion

​

Kinetic Energy

Travels in waves, is visible to us (we can see it).

travels in waves, is produced by vibrations
