Frictional forces are unavoidable in our daily lives.. Pros and cons of friction.. Magnitude of the maximum static frictional force is given by:. Magnitude of the kinetic frictional force is given by:. Friction. Friction is a force that opposes the motion, or tendency of motion, of an object.. Friction is caused . mostly by . the . electromagnetic . interactions of particles within molecules at the surfaces of objects in contact. While these interactions can be rather complex, their combined effects can be reasonably approximated with a decent amount of consistency.. October 29, 2014. Chapter 10 Forces. Force and Net Force.
