Energy Review

What is the difference between potential and kinetic energy?

• Potential is stored energy, kinetic is moving energy.

• Potential is moving energy, kinetic is stored energy

• Potential energy means it has potential, kinetic does not.

What are the two things that affect potential energy?

• Acceleration

What is the formula for kinetic energy?

• 0.5 x mass x speed²

• mass x gravity x height

• force x distance

• work / time

What is the formula for potential energy?

• 0.5 x mass x speed²

• mass x gravity x height

• force x distance

• work / time
