... The mass m moves vertically in response to the superposition of two forces, gravity mg (g = 9.8 m/s2) in the downward direction, and an upward normal force N exerted by the ground on the foot. Thus by Newton’s second law, the vertical component of its velocity vy obeys the equation: mdvy/dt = N – mg ...

... Thus, in uniform circular motion there must be a net force to produce the centripetal acceleration. The centripetal force is the name given to the net force required to keep an object moving on a circular path. The direction of the centripetal force always points toward the center of the circle and ...

... Coasting with no pressure on the accelerator: In theory if this was the case, you should move at a constant velocity eternally but on Earth this is not true as there are several resistance factors that cause the car to slow down and eventually come to rest. Air resistance and friction are the two ma ...
