Answer:
1. Friction can be a useful force because it prevents our shoes from slipping on the pavement when we walk and when we walk, friction is caused between the tread on shoes and the ground. This friction acts to grip the ground and prevent sliding.
2. friction stops car tires from skidding on the road.
3. When two surfaces slide over one another the tiny bumps push on each other. Friction causes a force on a surface which is in the opposite direction to its motion
4. Near the surface, friction reduces the wind speed, which reduces the Coriolis force. The weaker Coriolis force no longer balances the pressure gradient force and so the wind blows across the isobars toward lower pressure.
