Friction & Inclined Planes

Front

What direction does friction act relative to sliding down an inclined plane?

Back

In the opposite direction.

Front

What type of friction is not moving?

Back

Static friction.

Front

The formula for friction is: f = μN. What does the symbol μ represent?

Back

The coefficient of friction.

Front

How does friction affect speed?

Back

More friction decreases speed.

Front

True or False: The amount of friction depends on the weight of the objects pressing together.

Back

True.

Front

What is the definition of friction?

Back

Friction is the resistance that one surface or object encounters when moving over another.

Front

What are the two main types of friction?

Back

Static friction and kinetic friction.

Front

What is static friction?

Back

Static friction is the friction that exists between a stationary object and the surface it's on.

Front

What is kinetic friction?

Back

Kinetic friction is the friction between moving surfaces.

Front

What factors affect the amount of friction?

Back

The nature of the surfaces in contact and the normal force.
