## Ways to Reduce Friction & Ways to Increase Friction

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 […]

## Bearings to reduce friction and increase the efficiency of devices

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 […]

## How do Running shoes increase the force of static friction exerted by the ground on the athlete?

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 […]

## Friction Numericals – class 11 physics

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.

## Pushing a car, Newton’s 3rd Law and Friction

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 […]
