Contact Forces Quiz

A contact force is any force that occurs as a result of two objects making contact with each other.

Pushing a car or kicking a ball.

Contact forces are often decomposed into orthogonal components, one perpendicular to the surface(s) in contact called the normal force, and one parallel to the surface(s) in contact, called the friction force.

<p>No, not all forces are contact forces. The weight of an object is an example of a force that is not a contact force.</p> Signup and view all the answers

<p>Body forces, such as gravitational forces, electrical forces, and magnetic forces, can exist without contact occurring, unlike contact forces which require two objects to make contact.</p> Signup and view all the answers
