Frictional force


Friction definition

Friction definition Friction / Friction definition: If we either slide or attempt to slide a body over the surface of another body, electromagnetic forces act between the charged particles at the surfaces of the bodies which makes each body to exert a contact force on the other. The magnitudes of the contact forces acting on

Newton’s laws and Contact Forces between blocks – your must read

Newton’s laws & contact Forces between blocks in Mechanics Newton’s laws of motion gives us concepts of force (first law), measurement of force with its equation (second law), and reaction of force (3rd law). Today we will discuss an interesting topic of mechanics. It will cover a few interesting applications of Newton’s Laws and analyse

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?” Very often this question comes from the Physics students. Some asks, “How is friction useful sometimes?“ If we go by the common notion we have about Friction, certainly these questions may arise in young and eager minds who are trying

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

Pushing a car – Friction and Newton’s third law 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
