Kinetic friction force unit
WebFriction can be described as the force holding a moving object back. Kinetic friction interferes with the movement of multiple objects and is a part of everything in motion. The force is incident in a direction opposite to the sliding motion of an object. Things are not as we assume; even seemingly smooth surfaces are actually microscopic ... WebFriction. Friction is a contact force. It acts against the movement of an object. There are many examples of where friction is a useful force. For example, friction is why we do …
