Science > Physics > Friction > Applications of Friction In this article, we shall understand why does kinetic friction is smaller than the static friction and why it is easier to roll than solid. We shall also study some everyday examples in which friction is used. To produce relative motion between two bodies in contact […]

Friction

Science > Physics > Friction > Concept of Friction Friction or force of friction is a force which comes into existence when two bodies in contact have relative motion or tending to have relative with respect to each other and oppose the motion. Characteristics of Friction: Force of friction is always opposites to the force […]

Science > Physics > Force > Simple Numerical Problems on Force In this article, we shall study to solve numerical problems to calculate the magnitude of force, momentum, and change in momentum. Example – 01: The speed of a tortoise and hare are 1 m/s and 3 m/s respectively. The mass of the hare is 5 […]

Types of Forces

Science > Physics > Force > Types of Forces Depending upon the interaction between the bodies and level of contact forces are classified a) Contact forces b) Non-contact forces. Muscular force is a contact force. Electrostatic force is non contact force. Contact Forces: A force which can be applied only when it is in contact […]
