... REASONING AND SOLUTION Work and torque are both the product of force and distance. Work and torque are distinctly different physical quantities, as is evident by considering the distances in the definitions. Work is defined by W (F cos )s , according to Equation 6.1, where F is the magnitude of ...

... Friction is a force that opposes motion between two objects in contact. Friction can be a nuisance (e.g. it slows things down when you don’t want it to when driving a car or riding a bike). Friction can also be useful (e.g. brakes on a bike, and to enable us to walk). Experiment: To demonstrate fric ...
