The force of gravity on a 2-kg rock is twice as z9m 1 89;eesgc .sxw;2fekfgdb3 aqv8 great as that on a 1-kg iwftz0x la-)q+m 2m2 nrock. Why then doesn’t the heavier rock falltm-0 x lmzwi 2)nqa+2f 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.
