Category: 2. Friction

Friction finds application when matchsticks are ignited. Motion of pistons in a cylinder is an application of friction. It is possible to write on books and board as there is friction between pen and the board.

What Causes Friction? Friction is caused due to the irregularities on the two surfaces in contact. So, when one object moves over the other, these irregularities on the surface get entangled, giving rise to friction. The more the roughness, the more irregularities and more significant will be the friction. Types of Friction There are four…

Friction is a force that is dependent on external factors. Following are the two factors on which friction depends: 1. On the nature of the two surfaces that are in contactFriction is dependent on the smoothness or roughness of the two surfaces that are in contact with each other. When the surface is smooth, the…

Friction is defined as the resistance offered by the surfaces that are in contact when they move past each other. Friction provides traction that is needed to walk without slipping. Friction is helpful in most cases. However, they also offer a great measure of opposition to the motion. In addition, about 20 per cent of…

Friction When we throw a ball on the floor, it starts moving with some velocity. But ideally, no force should be acting in the direction of motion, and according to Newton’s first law, the ball should keep rolling, but this does not happen. Instead, the ball stops after moving a certain distance, so a force…
