(4) 11-25-24 Types of Friction

Front

What is friction?

Back

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

Front

What are the four main types of friction?

Back

The four main types of friction are static friction, sliding friction, rolling friction, and fluid friction.

Front

Define static friction.

Back

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

Front

Define sliding friction.

Back

Sliding friction is the friction that occurs when two objects slide against each other.

Front

Define rolling friction.

Back

Rolling friction is the friction that occurs when a solid object rolls across a surface.

Front

Define fluid friction.

Back

Fluid friction is the friction that occurs when an object moves through a fluid (liquid or gas).

Front

What is an example of static friction?

Back

An example of static friction is a book resting on a table that does not slide off.

Front

What is an example of sliding friction?

Back

An example of sliding friction is pushing a box across the floor.

Front

What is an example of rolling friction?

Back

An example of rolling friction is a bicycle tire rolling on the road.

Front

What is an example of fluid friction?

Back

An example of fluid friction is a swimmer moving through water.
