WebAn object accelerates when a force is acting on the object. This given by the Newton's second law F = m a, where F is the net force act on the object, m is the mass of the object and a is the acceleration of the object. The reason why objects accelerate as they fall is because the gravity of earth acts on the object. WebAcceleration is the change in velocity ÷ change in time Gravity accelerates all objects at the same rate (regardless of mass).
