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 investigation was designed to test the effects of which of the following forces?
Friction
Magnetism and friction
Gravity
Gravity and Magnetism
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. Which force acted upon the picture, causing it to fall?
Evaporation
Magnetism
Friction
Gravity
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?
The magnet will push the nails and bolts away from it.
Gravity will cause the magnet to pick up the nails and bolts.
The magnet will pull nails and bolts toward it.
Friction will cause the magnet to pick up the nails and bolts.
A man is kayaking in a river for a fun day of fishing. How does using the paddle affect the motion of the boat?
The friction between the paddle and water cause the boat to move forward.
Gravity causes the boat to move when the paddle is lowered down into the water.
Pulling the paddle causes the boat to move in the same direction of the pull.
Pulling the paddle causes the boat to move in the opposite direction of the pull.
