Give reasons for the following-
(a) We tend to slip when we step on a banana peel
(b) It is easier to push a lighter box than a similar heavy box on the same floor
(c) The force, needed to start a cart, is (somewhat) greater than the force
needed to keep it moving with a uniform speed
(d) Sportsmen use shoes fitted with spikes.
Answers
Answer:
Please see the answers below-
Explanation:
1. This is because a banana peel is slippery and tends to reduce the friction between our foot and the ground thus we tend to slip.
2. This is because lesser amount of force is needed to push the lighter box as compared to the heavier box.
3. This is because more force is needed to move a stationary object as compared to keep moving it.
4. This is because to increase the sportsmen's grip and reduce the friction between their foot and the ground.
Hope it helps and please mark as brainliest!
(A) We tend to slip on a banana peel because the surface of the peel acts as a lubricator which prevents the forces of friction, thus, we tend to slip down.
(B) It is easier to push a lighter box than that of heavier box because of the forces of friction and due to the heavy weight of the box, it is harder to move it, thus, the lighter box is easier to move.
(C) the force needed to start the cart is somewhat more because to overcome the forces of friction.
(D) Sportsman use shoes fitted with spikes to overcome wear and tear caused by friction.
Hope that helped you! stay safe!
