Force & Motion (Unit 4 Test Review)

A student wanted to see how his toy car would roll on different types of flooring. He decided to roll the car on a tile floor, a wood floor and a carpeted floor.

His experiment was designed to test the effects of which of the following forces?

• Gravity

• Friction

A teacher attaches pictures to the dry-erase board using adhesive tape during a sorting activity. The next day, one of the pictures was found on the ground.

A worker is constructing playground equipment for the park and dropped a box of nails and bolts. How will a magnet be helpful to the builder?

• Gravity will cause the magnet to pick up the nails and bolts

• Friction will cause the magnet to push away the nails and bolts

• The magnet will push the nails and bolts away from it

• The magnet will pull the nails and bolts toward it

A man is kayaking in a river for a fun day of fishing. How does using the paddle effect the motion of the boat?

• Pulling the paddle causes the boat to move in the opposite direction of the pull

• Pulling the paddle causes the boat to move in the same direction of the pull

• Gravity causes the boat to move when the paddle is lowered down into the water

• The friction between the paddle and water causes the boat to move forward
