Question

Can we get off a frictionless horizontal surface by jumping?

Answer 1

Friction: Friction is defined as the resistance offered by the surfaces that are in contact when they move past each other. The two factors on which friction depends are as follows: On the nature of the two surfaces that are in contact and On the force that is acting on these surfaces.

1. Friction comes in several forms: The force resisting the relative lateral movement of two solid surfaces in contact is called dry friction.
2. For instance, a human could only jump vertically up on a smooth, frictionless surface.
3. Since there is no friction pressing against him and preventing him from slipping, any force applied parallel to the surface will cause the person to slip.
4. If they can only move up and down, nobody can move sideways.
5. When one is in the air, blow out the air you earlier took in which will cause you to accelerate in the opposite direction.
6. As we walk, friction prevents our shoes from slipping on the ground and prevents automobile tires from skidding on the road. Walking causes friction as a result of the tread on your shoes rubbing against the ground.
7. Since there is no friction when you land, you will keep moving and keep sliding.

Therefore, when you will keep your motion and continue to slide because there is no friction when you land. You can only move up and down, but you can never move sideways (and fall down).
