Friction

Front

Static Friction is present only when an object is at rest.

Back

True.

Front

A 2.0-N force acts horizontally on a 10-N block that is initially at rest on a horizontal surface. The coefficient of static friction between the block and the surface is 0.50. What is the magnitude of the frictional force that acts on the block?

Back

2 N

Front

Can static and kinetic friction be present simultaneously?

Back

False
