WebFrictional force is force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. Friction makes it possible to do a lot of things like walking without sliding or falling. This is because, when the friction reduces between the ground and your shoes, that’s when you fall. WebForces and Newton's Laws of Motion. A flatbed truck is carrying a crate up a hill, as Figure 4.34 a illustrates. The coefficient of static friction between the truck bed and the crate is 0.350. Find the maximum acceleration that the truck can attain before the crate begins to slip backward relative to the truck.
