Grade 11 physics friction problems
WebThis choice of axes simplifies this type of problem, because there is no motion perpendicular to the slope and because friction is always parallel to the surface between two objects. The only external forces acting on the system are the skier’s weight, friction, and the support of the slope, respectively labeled w w, f f, and N N in Figure 4.12. WebWithout friction, they would not be able to accelerate, turn or brake. Friction can also be unhelpful. For example when the mechanical parts of a bike, like the chain and axles, rub …
