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 affect 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 cause the boat to move forward.
