Study Guide
Jeopardy Procedures/ Rules
• 1. Work in the group you are assigned.
• 2. When question is displayed every group must write answer
on their whiteboard.
• 3. The group that holds up their whiteboard first with the
correct answer gets chosen.
• 4. One random person in that group will be called on to
explain the answer- so make sure every knows why that is the
answer. – If your group gets it right you get the points and get
to pick the next question!
• 5. Most of the questions on this review are questions on
your green review sheet- write correct answers as we go
over them!

Identify the type of reaction…
$600
For every action there is a
reaction for example a rocket
launching.
Action and Reaction forces are
equal but act in opposite
directions.
Identify the type of reaction…

The boat will move backwards or in
the opposite direction. Action =
reaction.
Identify the type of reaction…
$1000
Bumper cars are in motion, an outside
forces stops the motion (Newton’s 1st
law) The cars move backwards because
of Newton’s 3rd law of motion- action =
reaction.

Earth has a greater mass then Mars and Mars
has a great mass than the moon. Therefore,
earth has more gravity then mars and Mars
has more gravity than the moon. Remember
Gravity has to do with distance and mass!
Good Luck
