## The Friction Coefficient | Coefficient of Friction

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 […]

## Friction definition

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 […]

## Newton’s laws | Contact Forces between blocks | Application of Newton’s laws

Application of newton’s laws: Newton’s laws of motion give us concepts of force (first law), measurement of force with its equation (second law), and the reaction of force (3rd law). Today we will discuss an interesting topic of mechanics – application of Newton’s laws. It will cover a few interesting applications of Newton’s Laws and […]

## How Friction helps in walking?-explanation with free body diagram

How friction helps in walking “If Friction is a force that opposes motion then how friction helps in walking?” As we walk we apply a contact force on the surface below and that surface also exerts an equal and opposite contact force on our foot or shoes. Depending on the position and angle of our foot, this […]
