We need to reduce or increase friction in different situations, depending on our requirements and benefits. Here, in this post, we will list down some efficient ways to reduce friction. Not only that, but we will also come up with some intelligent ways to increase friction as well to make our life better. Ways to […]
There are different ways to reduce friction. One way to reduce friction and increase the efficiency of devices such as generators, motors, and fans is to use bearings. Bearings are devices that allow surfaces to slide or roll across each other while reducing the force of friction. Many different types of bearings can be used […]
This post gives a preliminary idea of how physics fundamentals like friction and Newton’s laws of motion are involved in the design aspects of running shoes. Nowadays when sports have become so competitive, a pair of running shoes efficiently designed can bring a huge improvement in the performance of a runner. Here we will see […]
Here we will focus on solving numerical problems involving frictional force or friction and friction coefficient. We will take up a few sample problems as examples and solve those using the step-by-step process.

Friction / Friction definition: If we either slide or attempt to slide a body over a surface, the motion is resisted by a bonding (cold-weld) between the body and the surface. The resistance is considered to be a force called either the frictional force or simply friction. This force is directed along the surface, opposite […]
Hope you have seen people pushing their car when it’s not starting due to some issue. When someone is pushing a car or something like that, he first pushes the ground or floor obliquely backwards with his feet. Following the ‘3rd law of Newton‘ the ground also exerts an equal and opposite force obliquely on […]
