17.5 Acceleration and Newton`s 2nd law of motion
... About 100 years later, Newton’s second law explained why. A heavy object experiences a stronger pull from gravity than a light object, but it also has more inertia which makes it harder to get moving! The two effects cancel out, so all objects fall to Earth a = F1/m1 = F2/m2 with the same accelerati ...
