WebFriction happens when two surfaces move over one another. Also, it is a force that resists the motion of an object. Moreover, it causes motion energy to be lost in the form of heat. Besides, we use the coefficient of friction to … Weban inequality; namely, that the static friction force is less than or equal to the coefficient of static friction times the normal force. Note the important difference between kinetic fS ≤µS N and static friction: the kinetic force is always equal to µKN, while the static force is NOT always equal to µS N . small heat generatorsWebFriction allows us to move, which you have discovered if you have ever tried to walk on ice. There are different types of friction—kinetic and static. Kinetic friction acts on an object in relative motion, while static friction acts on an object or system at rest relative to each other. small heat gun for shrink tubing

"WebAs we discussed before, friction is unlike gravity and electromagnetism which are fundamental forces. Scientists say that it is the result of the electromagnetic attraction between charged particles in two touching surfaces. Actually, the law which governs it started to form in the 1400s by scientists. " - Notes of friction
