For the following situations, describe the contact and non-contact forces that are involved.

Situation
Contact Force(s)
Non-Contact Force(s)
A book sitting on a shelf






A soccer player kicking a ball; the ball soaring through the air and landing on the ground






A hiker in the woods reading her compass to determine which direction to go






A child on a sled; first, the child is sitting at the top of the hill, waiting his turn; then, the child pushes off and slides down the hill, eventually coming to a stop.

A book resting on a shelf: contact force- reaction force

non contact force: gravitational force

Soccer ball- contact force- air resistance

non contact force- gravitational force

Compass- contact force- reaction force

non contact force- magnetic force

child on sled- contact force- friction

non contact force- gravitational force
