plzllzlzlz ansrrrr
question s
1) force of friction will increase between two surfaces when they are pressed harder against each other
2) Among the sliding friction ,static friction and Rolling friction , static friction is highest and Rolling friction is least
3) People doing "ice Skating" wear skis
4) anita had a cycle with a jammed chain . it had became vry hard for her to pedal . she applied a lubricant to decrease the friction
5) we rub our hands together when its cold . By doing so our muscles release energy and we feel warm
6) Proper grooving of tyres of a vehicle is done to increase the speed by minimizing friction between the tyres and the road.
7) it is easier for a horse to pull cart during the first few steps and then it becomes harder once the cart sets into motion
8) machine parts get jammed In summer and work smoothly in winter
9) fast moving vehicle are made broader in the front
10) Walking would have been much easier without friction

Answer:
Explanation: Friction between two surfaces increases when they are pressed harder because there are irregularities between two surfaces which tries to lock the two surfaces. When two surfaces are rubbed harder then irregularities get more time to increase their contact which in turn lead to increased friction.
