## 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.

## The Friction Coefficient | Coefficient of Friction – questions, answers for class 11

This post is entirely focused on the Friction coefficient (also known as the coefficient of friction). We will define it and find out its types. Also, we will derive equations and get a list of values. Please note the symbol μ(mu) which denotes this coefficient. What is the friction coefficient? The Friction coefficient is a […]
