Friction- 5th Grade

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 type of surfaces have less friction?

Back

Smooth surfaces have less friction compared to rough surfaces.

Front

True or False: Smooth objects have less friction than rough objects.

Back

TRUE

Front

What is an example of friction?

Back

Using the brakes on your bike to slow down is an example of friction.

Front

Which of the following is NOT an example of friction?

Back

A satellite traveling through deep space is NOT an example of friction.

Front

Why does a rolling ball stop?

Back

A rolling ball stops due to friction acting against its motion.

Front

What force makes it harder to slide down a hill?

Back

Friction makes it harder to slide down a hill.

Front

What is the effect of rough surfaces on friction?

Back

Rough surfaces increase friction, making it harder for objects to move.

Front

How can friction be reduced?

Back

Friction can be reduced by using lubricants, such as oil or grease.

Front

What is static friction?

Back

Static friction is the force that keeps an object at rest and prevents it from moving.
