Vocabulary
What is Energy
Energy from moving electrons.
What is electrical energy
This factor increases potential energy when it increases
What is Height?
Kinetic Energy depends on these two things
What is Mass and Velocity
This type of energy is used when you eat food and your body moves.
What is chemical energy
This is stored energy based on position or condition.
What is Potential Energy
What is electromagnetic energy
The formula used to calculate Potential Energy

What is electrical to light
This is Energy of motion.
What is Kinetic Energy
Energy stored in food and fuel.
If Mass increases, potential energy does this.
What is increases
If velocity doubles, Kinetic energy does this.
What is increases
