Friction

Front

What is Static Friction?

Back

Static Friction is the friction that acts on stationary objects.

Front

What causes Friction?

Back

Friction results from uneven surfaces in contact with each other.

Front

What is an Applied Force?

Back

An Applied Force (Fa) is a force that is a push or a pull.

Front

What does Frictional Force do?

Back

Frictional Force (Ff) opposes the direction of motion.

Front

In which direction does Friction act?

Back

Friction acts in the opposite direction of movement.

Front

What is Kinetic Friction?

Back

Kinetic Friction is the friction that acts on moving objects.

Front

What is the Normal Force?

Back

The Normal Force (Fn) is the force perpendicular to the surface of contact.

Front

How does surface roughness affect Friction?

Back

Rougher surfaces generally increase friction, while smoother surfaces decrease it.

Front

What is the coefficient of friction?

Back

The coefficient of friction is a numerical value that represents the frictional force between two surfaces.

Front

What is the difference between Static and Kinetic Friction?

Back

Static Friction acts on stationary objects, while Kinetic Friction acts on moving objects.
