Viscous friction is

• When motion is slowed down in the air

• When motion is slowed down in water

• When the rolling of an object is slowed down

The type of friction occurring when an object is not moving

• Static Friction

• Rolling Friction

• Air Friction

• Sliding Friction

Which of these is an example of sliding friction?

• Swimming to the bottom of a pool

• A cup sitting still on a table

• Putting on a pair of sandles

• Throwing a ball through the air

A roller coaster that is in motion is an example of

• Kinetic energy

• Potential energy

Newtons 3rd Law explains 

• For every action, there is an opposite but equal reaction

• F = M * A

• Inertia

• An object in motion stays in motion unless acted upon by an outside force
