The bowling ball has the same inertia whether it's standing still or moving, so throwing it and catching it are both equally difficult. • ...

... His 2nd law said that the force applied to an object is directly proportional to its acceleration and that as an object grew in mass it would be harder to make accelerate. So mass becomes the property of a body that resists change in motion. This is summed up by the equation: Force (N) = mass (kg) x ...
