The force of gravity o ssvz*h:d:1 p*vktht( 46ggsbn a 2-kg rochik999 .sr4me qoted-k is twice as great as that on a 1-kg rock. Why then doesn’t the heavier rockie9h 9t9-.mr do4qs ek 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.
