Question

Why is it difficult to climb up a Greasy Pole?

Answer 1

Hint:Friction is the force exerted by two surfaces moving (or attempting to slide) over one another. The level of friction is determined by the materials used to make the two surfaces. Friction is increased as the surface becomes rougher.

Complete answer:
In climbing, friction is the main element. It's what lifts us off the ground and allows us to execute small weight changes and delicate sequences. Friction in climbing is proportional to the contact area (more contact equals more friction).

Grease reduces friction between surfaces that come into contact. An individual uses frictional force to keep himself or herself on the pole when climbing up it. As the pressure between the pole and the person decreases, the person can lose the ability to hang on to the pole. As a result, climbing a greasy pole is tough.

In basic terms, climbing a greased pole is dangerous because as we ascend a pole, there can be a force of friction that assists us in climbing the pole, but the grease on the pole reduces the friction to a very low level. As a result, we are unable to secure a hold on the pole, making climbing impossible.

Note:When two irregular surfaces come into contact, friction is created. The constant grinding of these surfaces together allows them to wear out with time in machines. In that case, lubricants like oil or grease should be used to minimise friction between the materials.
