friction (ˈfrɪkʃən) n 1. (General Physics) a resistance encountered when one body moves relative to another body with which it is in contact 2. the act, effect, or an instance of rubbing one object against another 3. disagreement or conflict; discord 4. (Phonetics & Phonolog...
Force Force of friction Friction Homework Physics Physics homework Work Work done In summary, Joe exerts 11400 J of energy to drag a crate 25 m across the floor at a constant speed. The rope making a 48 degree angle with the horizontal means that the force exerted on the crate is equal ...
These calculations consider a simplified picture of friction. There are many other factors that influence the static and kinetic friction force. Friction does not usually behave simply, and the coefficients of friction often change depending on external conditions or deviation from a constant speed in ...
