Friction

Front

The friction between two surfaces can be given as a ratio of the frictional force (Ff) to the normal force (Fn). This is called ____________.

Back

coefficient of friction

Front

Kinetic Friction is also called...

Back

Sliding Friction

Front

Static Friction is friction of...

Back

stationary objects

Front

This force opposes the direction of motion.

Back

Frictional Force (Ff)

Front

Friction is a force that acts in a ___________ direction of movement.

Back

opposite

Front

What is the formula for calculating the coefficient of friction?

Back

Coefficient of Friction (μ) = Frictional Force (Ff) / Normal Force (Fn)

Front

What are the two main types of friction?

Back

Static Friction and Kinetic Friction

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on stationary objects, while kinetic friction acts on moving objects.

Front

What factors affect the amount of friction between two surfaces?

Back

Surface roughness, normal force, and the materials in contact.

Front

What is the role of friction in everyday life?

Back

Friction allows us to walk, drive, and hold objects without slipping.
