state and explain with example how friction can help the cause of motion in certain situation
Answers
Explanation:
We can walk on the road and floor due to friction. Also, the vehicles run on the road due to friction between their tyres and road. We slip and the vehicles skid in absence of friction. Thus, friction can cause the motion in these situations.
Because without the help of friction, nothing will stop and everything will always be in motion.
This also explains why we cannot hold a glass with oily hands. Our hands are greasy and smooth and we know that a smooth surface offers lesser interaction with the glass. And hence, it tends to slip.
Another example of this is that while trekking on hilly and watery terrains, we wear groovy sports shoes so that rough shoes establish better locking with the hilly trains, increase friction, provide more grip and decrease chances of a slip. here also friction is the cause of being able to trek.
