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 surface.

Front

What are the main types of friction?

Back

The main types of friction are static friction, sliding (kinetic) friction, rolling friction, and fluid friction.

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 sliding (kinetic) friction?

Back

Sliding friction is the force that opposes the motion of an object that is sliding over a surface.

Front

What is rolling friction?

Back

Rolling friction is the force that opposes the motion of an object that rolls over a surface.

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 surface texture affect friction?

Back

Rough surfaces generally create more friction than smooth surfaces due to increased contact area.

Front

What is air resistance?

Back

Air resistance is a type of fluid friction that acts on objects moving through the air.

Front

How does weight affect friction?

Back

In general, the greater the weight of an object, the greater the frictional force acting on 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.
