Answer:

Explanation:

Two situations where it is desirable to increase friction are:

1.Tyres have designs and patterns with grooves on the surface to increase fraction with the road. This presents slipping of the tyres on the wet road.

2.Spikes are provided in the soles of shoes used by players and athletes to increase friction so that they get a firm grip on the ground.
