The Law of Conservation of Energy states:
Energy can be created or destroyed, but not transformed
Energy cannot be created or destroyed, it can only be transformed
Energy can't be created, destroyed or transformed
Energy cannot be created or destroyed.

Consider a basketball being held above the ground. It has 1000 joules of energy. The ball is dropped and bounces until it stops. Select all of the following that are true about the basketball.
When the ball stops bouncing, it has used 1000 joules of energy
The ball started with gravitational energy
When the ball stops bouncing, it has used 500 joules of energy
The ball had mechanical, elastic, and sound energy as it bounced
You buy an electric car that plugs into the wall to get energy. Your house has solar panels on the roof to generate energy to charge the car. What energy transformation is taking place to charge the battery in your electric car?
radiant ----> electrical ----> chemical
thermal ----> electrical ----> chemical
radiant ----> electrical ----> nuclear
electrical ----> chemical ----> radiant
Which items would have this energy transformation: chemical energy -> mechanical, sound, and thermal energy?
driving a car
candle burning
windmill turning
playing a violin

An engineer is trying to build a quieter jackhammer. The Jackhammer uses 300 Joules of energy a second. It makes 150 Joules of mechanical energy, and 50 Joules of thermal energy. Assuming the only other type of energy present is sound, how much sound energy is there?
1 Joule
100 Joules
200 Joules
30 Joules
