two objects a and b have the same size but a is heavier than b .they reach the ground at the same time but a has greater______
In this scenario, since both objects A and B have the same size but A is heavier than B, they will experience the force of gravity pulling them towards the ground with the same acceleration. This means they will reach the ground at the same time.
However, since object A is heavier, it will have a greater gravitational force acting on it compared to object B. The greater force acting on object A will result in a greater impact or "heaviness" when it hits the ground. Thus, the missing word in the sentence would be "impact" or "force of impact".
