Tension
The force that tends to pull things ; apart also known as a tensile force
Normal Force
The force exerted by a surface on an object in contact with the surface. It is always perpendicular to the surface
Apparent Weight
A measurement of weight that a system that is submerged or floating in a fluid is acted on by an upward buoyant force equal in magnitude to the weight of the displaced fluid
Friction
A contact force that opposes motion between objects trying to slide past each other
Coefficient of Friction
The measure of how difficult it is for matter to slide relative to each other
Kinetic Friction
The frictional force between objects that are sliding past each other
Static Friction
The frictional force between objects that are trying to slide past each other but are not moving relative to each other
Rolling Resistance also known as Rolling Friction
The cumulative effect of all restrictive forces that reduces the freedom of motion of a rolling object ; also known as ( rolling resistance ) ( Rolling Friction )
