Understanding Friction and Forces

Front

Friction

Back

The resistance that one object encounters when moving over another; a force that opposes motion.

Front

Force

Back

A push or pull exerted on an object.

Front

Contact Force

Back

A force that is applied when two objects physically touch each other, such as friction or tension.

Front

Sliding friction

Back

Friction that occurs when one solid surface slides over another

Front

Rolling Friction

Back

Friction that occurs when an object rolls over a surface

Front

Fluid Friction

Back

A friction force that opposes the motion of an object moving through a liquid or gas

Front

Air Resistance

Back

The fluid friction experienced by objects falling through air (a gas).

Front

Static Friction

Back

The friction between a non-moving object and the surface that it is resting on. (highest friction)

Front

Lubricant

Back

A substance that reduces friction on surfaces

Front

Weight

Back

A measure of the gravitational force pulling on an object
