Friction Flashcard

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

How does friction affect speed?

Back

More friction decreases speed.

Front

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

Back

False.

Front

What happens when there is less friction?

Back

Objects can move more easily and faster.

Front

Which material increases friction on a bicycle ramp?

Back

Rough paper.

Front

What do rougher surfaces have compared to smoother surfaces?

Back

Rougher surfaces have greater friction.

Front

What is an example of a surface with low friction?

Back

Ice is an example of a surface with low friction.

Front

What is an example of a surface with high friction?

Back

Sandpaper is an example of a surface with high friction.

Front

How can friction be reduced?

Back

Friction can be reduced by using lubricants like oil.

Front

What is the effect of gravity on friction?

Back

Gravity can increase the amount of friction between two surfaces.
