Which force will stop a moving skateboard?

• friction

• inertia

• newtons

• balanced forces

Which describes a change that will likely occur in the collision below?

• Kinetic energy will be transferred from the nail to the hammer, causing the hammer to move.

• Kinetic energy will be transferred from the hammer to the nail, causing the nail to move.

• Potential energy will be transferred from the nail to the hammer, causing no change in motion.

• All of the kinetic energy will transform into light energy and no change in motion will occur.
