Friction Review

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another surface.

Front

What are the two main types of friction?

Back

The two main types of friction are static friction (when an object is not moving) and kinetic friction (when an object is moving).

Front

What is static friction?

Back

Static friction is the force that keeps an object at rest and prevents it from starting to move.

Front

What is kinetic friction?

Back

Kinetic friction is the force that opposes the motion of an object that is already moving.

Front

What is rolling friction?

Back

Rolling friction is the force that opposes the motion of a rolling object, such as a ball or a wheel.

Front

What is fluid friction?

Back

Fluid friction is the resistance encountered by an object moving through a fluid (liquid or gas).

Front

How does friction affect motion?

Back

Friction slows down moving objects and can eventually bring them to a stop.

Front

What is an example of increasing friction?

Back

Applying sand to a slick surface to prevent slipping is an example of increasing friction.

Front

What happens to a soccer ball when it rolls on the ground?

Back

The ball eventually stops due to the force of friction acting against its motion.

What type of friction do wheels on a dolly experience?

Back

Wheels on a dolly experience rolling kinetic friction.
