PICTIONARY JEOPARDY

Draw a FBD for an object feeling the force normal force acting in the same direction as the gravitational force.

Where could this happen?

How does this object move?

PICTIONARY JEOPARDY

Draw a FBD for an object feeling the force normal force acting 135° away from the gravitational force. If this object is at rest, what else do you know?

Where could this happen?

FINAL ROUND

Label the magnets 1 (bottom) through 5 (top).

Draw FBD for each. Hint: the magnetic force gets

weaker as magnets get further apart.
