Look at the image. Which of the following best identifies and describes the force shown?

• A. The apple is being pulled toward the ground by gravity due to the strong gravitational force of Earth
• B. The apple fell from the tree and toward the ground due to friction of the wind pushing past the apple.
• C. The apple is being pulled toward Earth due to the strong magnetic pull of Earth.
• D. The apple is being pushed toward Earth due to applied forces once it breaks free from the branch.

A metal paper clip lying still on a desk is acted on by multiple forces. When a magnet is brought close to the paper clip, it moves toward the magnet. Select all options that identify and describe the forces acting on the paper clip.

• A. Friction between the desk and paper clip causes it to stay still before the magnet acts upon it.
• B. Magnetic force between the paper clip and magnet causes the paper clip to be pulled toward the magnet without the need for contact
• C. Normal contact force between the desk and paper clip before the paper clip is acted on by the magnet
• D. Gravitational force pulls the paper clip down toward the Earth as it rests on the desk due to its great mass.
