Applications of Newton's Laws (Physics)

Recall cards on applying Newton's laws: the systematic problem-solving strategy of sketching the situation, drawing a free-body diagram of the external forces, applying Newton's second law per coordinate axis, and checking the result; static and dynamic equilibrium, tension in a massless string over a frictionless pulley, apparent weight and elevator problems, and connected objects. Friction as a contact force opposing relative motion, static versus kinetic friction, the laws f_s <= mu_s N and f_k = mu_k N, the dimensionless coefficients of friction, area independence, and the microscopic origins of friction. Centripetal acceleration and force in uniform circular motion, F_c = m v^2/r = m r omega^2, ideally banked curves with theta = arctan(v^2/rg), inertial versus noninertial reference frames, and the fictitious centrifugal and Coriolis forces. And drag force through a fluid, F_D = (1/2) C rho A v^2, the drag coefficient, terminal velocity v_T = sqrt(2mg/(rho C A)), and Stokes' law for small slow objects.
