GRADE 6 FRICTION

Front

This type of force resists motion between two surfaces that are pressed together.

Back

Friction

Front

Which type of friction is shown in the picture?

Back

Fluid Friction

Front

You can move heavy boxes by sliding them over the ground, or you can put them on a dolly and then roll them over the ground. Which way makes it easier to move the boxes? Why?

Back

Rolling the boxes over the floor on the dolly is easier because rolling friction is less than sliding friction.

Front

The weakest type of friction that occurs between solid surfaces is _____ friction.

Back

rolling friction
