Energy

Genius is that energy which collects, combines, amplifies, and animates.

Samuel Johnson

• Energy is the ability to do work or cause change
• Caused by forces

 

• There are two types of energy:
• Kinetic Energy - the energy of motion
• Can be increased
• Increasing speed
• Increasing mass
• Potential Energy - is stored energy - it has "potential" to do something
• Elastic potential energy - elastic can store energy and convert it to motion when it is released.
• Gravitational potential energy - is the energy an object has when we raise it off the ground.
• Chemical potential energy is the energy stored in chemical bonds of molecules
• Can be increased
• Increasing height
• Increasing mass

 

• Forms of energy
• Electrical
• Mechanical
• Chemical
• Nuclear
• Radiant
• Thermal
• Conservation of energy
• Energy is not created or destroyed
