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: 1. Static Friction 2. Sliding Friction 3. Rolling Friction 4. 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 friction?

Back

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

Front

What is rolling friction?

Back

Rolling friction is the force that opposes the motion of an object rolling over a surface, such as wheels.

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 speed?

Back

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

Front

What happens to a marble rolling down a path with no friction?

Back

The marble would remain at a constant speed.

Front

How can you decrease the amount of friction?

Back

You can decrease friction by making the surface smoother.

Front

What is the effect of increasing weight on friction?

Back

Increasing the weight or force pushing surfaces together increases the amount of friction.
