उत्तर
Ways by which friction can be increased are :
- Tires of all vehicles have grooved designs or treads to make their surface rough. The roughness of a surface increases friction and prevents a vehicle from slipping or skidding on a wet or muddy road.
- Spikes in the shoe soles used by players and athletes increase friction and they get a firm grip on the ground. The soles of footwear are also provided with grooved designs to increase friction and avoid slipping.
- The handles of motorbikes are covered with spiked rubber to provide a good grip and have better control in holding the handles.
