non-contact force

Back

a force that one object can apply to another object without touching it

Front

contact force

Back

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

Front

static friction

Back

the force that resists the initiation of sliding motion between two surfaces that are in contact and at rest

Front

sliding friction

Back

friction that occurs when one solid surface slides over another

Front

fluid friction

Back

a friction force that opposes the motion of an object through a fluid

Front

air resistance

Back

The combination of all forces acting on an object

Front
