Energy Pretest

Why can't the skater reach the same point where he was release when he goes up the other side of the ramp?

• The skater experiences friction which is creating thermal energy as well as kinetic energy.

• The skater is slowing down due to his mass.

• The skater is getting tired and wants to stop.

• none of the choice are correct.

In the evening/night, Anthony used a flashlight to go on a walk with his family. Sadly, he forgot to turn the flashlight off. In the morning, his father said, "The flashlight has a dead battery now. We need to replace it."

This means the energy that was stored in the battery -

• Disappered into nowhere

• Was destrogy

• Was changed into other forms of energy

• Was used to create a new forms of energy

• Transferred from place to place

• Transferred through contact between objects

• Transformed from sound to work

• First created and then destroyed.
