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 four types of friction?

Back

The four types of friction are static friction, sliding 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 moving when a force is applied.

Front

What is sliding friction?

Back

Sliding friction is the force that opposes the motion of an object as it slides over a surface.

Front

What is rolling friction?

Back

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

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 have greater friction compared to smoother surfaces due to increased contact area.

Front

How does friction affect speed?

Back

More friction decreases speed, while less friction allows for greater speed.

Front

What type of friction do swimming fish experience?

Back

Swimming fish experience fluid friction as they move through water.

Front

On which surface will a toy car travel the furthest?

Back

A toy car will travel the furthest on a polished wood surface due to less friction.
