Front

How does friction affect speed?

Back

More friction means slower speed.

What type of surface has less friction for ice skating?

Back

A smooth ice rink.

Front

What happens on rougher surfaces?

Back

Rougher surfaces have more friction.

Front

How do the bumps and grooves on shoes help us?

Back

They help keep us from falling easily.

Front

True or False: The rougher the surface, the faster an object will travel.

Back

False.

Front

What is an example of a surface with high friction?

Back

A rough concrete area.

Front

What is an example of a surface with low friction?

Back

A smooth ice rink.

Front

What can increase friction between two surfaces?

Back

Adding weight or using rougher materials.

Front

What is the effect of lubrication on friction?

Back

Lubrication reduces friction.
