it is actually equal to the gravitational acceleration at that point.
而在实际上等于该点物体所受的重力加速度。
if i weigh myself on the moon where the gravitational acceleration is six times less then i would weigh six times less-- so far, so good.
如果在月球上称,重力加速度就,只有地球的1/6,我的重量,也只有1/6,没什么问题。
so we could now calculate how fast we have to rotate this space ship - to mimic the gravitational acceleration on earth-- 2 which is 9.8 meters per second squared.
这样我们就可以计算一下,大概要旋转多快,才能模拟出地球的重力加速度-,模拟出9。8米/秒。
when we have gravity an object is influenced by the gravitational acceleration and the gravitational acceleration is a constant.
当我们考虑到重力时,物体受重力,加速度影响,重力加速度,是一个常数。
now, you may remember that we dropped an apple from three meters and that we calculated the gravitational acceleration given the time that it takes to fall.
你们也许记得,从,3m高的地方扔的苹果,我们算出重力,加速度,给出,下落的时间。
the string will say 「aha! i'm going to pull now on this person 」because the gravitational acceleration alone is not enough-- i need some extra pull."
绳子会说,“啊哈,这家伙需要我来帮忙拉了“,因为此时只靠重力加速度,不足以提供向心加速度了,需要额外的补充
is it obvious that the gravitational acceleration is independent of all these quantities?
重力加速度不受,这些量的影响,这个结论明显吗?
methods for accurate gravitational acceleration measurement are presented, which are viscous force modified method and viscous force offset each other method.
本文介绍了用粘滞阻力修正法和粘滞阴力互相抵消法来精确地测量重力加速度。
ten times further away, the gravitational acceleration is down by a factor of 100.
远上十倍,重力加速度,就会减少100倍。
if you really want to recalculate the gravitational acceleration using our data, you should really subtract the two milliseconds from the time.
如果你想用我们的,数据重新计算重力加速度,你需要从这个,时间里减去2毫秒。
and so you see that the gravitational acceleration that i experience at different distances at different distances from the sun, is inversely proportional with r squared.
因此你看到,我承受的重力加速度,距离地球不同远近,距离太阳的不同距离,和r的平方成反比。
and this must be larger or equal to the g gravitational acceleration g.
这个必须大于,或等于,重力加速度。
