Forces and Motion Quiz

What is a contact force?

• A force that acts at a distance

• A push or a pull on one object by another that is touching it

• An attractive force between objects with mass

• A force that resists motion between surfaces

• Pressing the keys on a computer keyboard

• Pushing someone on a swing

• A plate sitting on a table

What is the normal force?

• A force that acts without touching

• The support force exerted on an object that touches another stable object

• An attractive force between magnets

• A force that resists sliding motion

Which of the following is a real-world application of noncontact force?
