Question

2. State two ways in which friction is useful.​

Answer 1

Friction can be a useful force because it prevents our shoes slipping on the pavement when we walk and stops car tyres skidding on the road. When you walk, friction is caused between the tread on shoes and the ground. This friction acts to grip the ground and prevent sliding. Sometimes we want to reduce friction.

Answer 2

Answer:

=> It helps us have a grip while walking.

=> Stops car tires skidding on the road.

Hope this helps!! :)
