WebSep 30, 2024 · Problem (1): A constant force of 10\, {\rm N} 10N is applied to a 2- {\rm kg} 2−kg crate on a rough surface that is sitting on it. The crate undergoes a frictional force against the force that moves it over the surface. (a) Assuming the coefficient of friction is \mu_k=0.24 μk = 0.24, find the magnitude of the friction force that opposes the ... WebFriction Force F frict. The friction force is the force exerted by a surface as an object moves across it or makes an effort to move across it. There are at least two types of friction force - sliding and static friction. Though it is not always the case, the friction force often opposes the motion of an object.
