Force of gravity practice problems
WebFrictional force is defined as frictional coefficient x normal force. In this instance normal force is equal and opposite to Gravitational force which is equal to mass x gravity constant. So if you substitute all of this in you are left with two equations, assuming frictional force is equal to the total force. a=Ff/m.
