Friction Flashcard

Front

What is friction?

Back

Force that opposes motion.

Front

How does the roughness of a surface affect the force of friction?

Back

The force of friction increases.

Front

What type of friction is not moving?

Back

Static friction.

Front

How does the weight of an object affect the force of friction?

Back

The force of friction increases with the weight of the object.

Front

Which type of friction occurs when an object is in motion?

Back

Kinetic friction.

Front

What is static friction?

Back

The frictional force that prevents two surfaces from sliding past each other when at rest.

Front

What is kinetic friction?

Back

The frictional force acting between moving surfaces.

Front

What factors affect the force of friction?

Back

Surface roughness and the normal force (weight of the object).

Front

What is fluid friction?

Back

The resistance encountered by an object moving through a fluid (liquid or gas).

Front

What is rolling friction?

Back

The frictional force that occurs when an object rolls over a surface.
