Energy Transfer Retest

According to the law of _________________, energy cannot be created nor destroyed, but can be transfered.

• Conservation of Energy
• Inertia
• Acceleration
• Conservation of matter

Mechanical energy is...

• energy built up before being in motion
• energy released in a chemical reaction
• sum of kinetic and potential energy
