What is friction?

Back

Friction is the force that opposes the motion of an object when it is in contact with another surface.

Front

What is normal force?

Back

Normal force is the support force exerted upon an object that is in contact with another stable object.

What is the relationship between force and motion according to Newton's First Law?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.
