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, click
the 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,

Explain the action and reaction
forces when a hammer hits a nail.

and the nail hits the
hammer.

A volleyball player bumps
the ball. The forces are equal
and opposite, explain why
the motion is not.
Answer
Back to
Game Board
The forces are equal and opposite, but the objects the forces are
being placed on are not. They have differing amounts of mass,
and therefore different amounts of inertia. The one with the
least inertia moves the most.
