The force of gravity on a 2-kg rock is twice aso) cpzc,/g bc3(pl ds l*m.iu. a3 f:bigsx*+sg t.l8bgreat as that on a 1-kg rock. Why then doesn’t the*.xg f +t 3gbil:asb8s heavier rock fall faster?
参考答案:
The acceleration of both rocks is found by dividing their weight (the force of gravity on them) by their mass. The 2-kg rock has a force of gravity on it that is twice as great as the force of gravity on the 1-kg rock, but also twice as great a mass as the 1-kg rock, so the acceleration is the same for both.
