Welcome to Forces and Motion Jeopardy!
I’m your happenin’ host Sal the Scientist! Today we will be learning about the Newton’s laws of motion! He was one smart dude!
Instructions Game Board
Choose from one of five categories. Then choose a point value. The larger the value, the more difficult
the question. Choose from one of four answers.When you are finished with each question, clickthe home button to go back to the game board.If you are playing as a team, the team with the
most points wins! Have fun, and remember,

What would happen to the momentum of a car if it rear ends a
parked car?
Answer
Back toGame Board
Back toGame Board
The momentum is transferred
to the parked car.
What does the law of conservation of momentum state?
Answer
Back toGame Board
Back toGame Board
The total momentum of any group of objects remains the same or is
conserved.
What happens to momentum when a moving train connects to
another train?
Answer
Back toGame Board
The two trains move together sharing the velocity.
Momentum is conserved
