Question

Discuss two ways each to increase and decrease the friction between any two surfaces

Answer 1

Answer:

increase:

• Press the two surfaces together harder.

• Stop any relative motion.

• Remove lubrication between the two surfaces.

• Remove wheels or bearings to create sliding friction.

decrease:

• Make the surfaces smoother.

• Lubrication is another way to make a surface smoother.

• Make the object more streamlined.

• Reduce the forces acting on the surfaces.
