1. When an object slides down a hill, not all of its potential energy turns into kinetic energy. Explain this using the Law of Conservation of Energy. Why is this?

DO NOW

The Law of Conservation of Energy says that energy

cannot be lost or destroyed. When the potential energy does not entirely transform

to kinetic energy, it is usually because of friction causing

the potential energy turn into sound energy and thermal

energy.

RULES OF THE GAME

• One clipboard & dry erase marker for every two people (take turns writing)

• You are only sharing answers with that one partner, not with your whole team

• Only write ‘A’ ‘B’ or ‘C’ on your dry erase board

• You will need a sheet of scrap paper for you and your partner (to do solve math problems on)

• When the teacher says “Boards!” your board must go, or your answer will not be counted

SCORING

• Teams will be divided up based on rows

• Even though you have a whole row as your team, you’re only able to share answers with your partner

• Whichever row has the MOST correct answers will receive the point for that round

• If there is a tie, both teams will receive a point
