This is the stopping force that opposes the relative movement or the tendency of relative motion of two solid surfaces, fluid layers, and material elements when they slide each other, known as friction. It acts tangentially along with the contact. Friction always exists in pairs. On microscopic observation, we find…
We can understand sliding friction as the resistance force created between any two bodies when sliding against each other. This friction is also called kinetic friction and it is defined as the force that is required to keep a surface sliding along another surface. It hangs on two variables-…
When surfaces in contact move relative to each other, the friction between the two surfaces converts kinetic energy into thermal energy (that is, it converts work to heat). This property can have dramatic consequences, as illustrated by the use of friction created by rubbing pieces of wood together to start…
