(2) The size of the object doesn't determine the coefficient of friction! If I slide a cube along a table, and another cube of the same weight but twice the size, the force of friction doesn't change. WebWhat is kinetic friction? When two objects moving along each other and rubbing one another, they are subjected to kinetic friction. It is a force that exists between moving surfaces. The kinetic friction coefficient is denoted as μk. The unit of friction is Newton N. The force between two non-moving objects is called static friction.

WebDec 22, 2024 · The most straightforward kinetic friction definition is: the resistance to motion caused by the contact between a surface and the object moving against it. The force of kinetic friction acts to oppose the motion of the object, so if you push something forward, friction pushes it backwards.
