Question

give three ways to increase and reduse friction?

Answer 1

Methods of reducing friction:

1) Friction can be reduced by making the surface smooth by polishing.

2) Friction can be reduced by applying lubricants (like oil or grease) to the rubbing surface.

3) Friction can be reduced by using wheels to move objects.

Methods to increase friction:

1) Create a “rougher” or more adhesive point of contact.

2) Press the two surfaces together harder.

3) Remove lubrication between the two surfaces.
