Guest Posted February 9, 2011 Report Share Posted February 9, 2011 7 Pens, all identical in size shape and build, are dropped in the same area of the moon, at the same time. They don't all land at the same time. Why? Quote Link to post Share on other sites

0 Guest Posted February 10, 2011 Report Share Posted February 10, 2011 The pens would have to have different masses. Just becuase they look the same, doesn't mean they are the same... They could have different amounts of ink in the cartridge or made with different materials... Quote Link to post Share on other sites

Actualy, while the strength of the gravitational pull may be different, the rate of acceleration in a vacuum is the same. I believe they did an experiment to prove this with a hammer and a feather on the moon. That said:Dropped at different times. Quote Link to post Share on other sites

Famous experiment (on the moon) where a hammer and a feather were dropped from the same height at the same instant and both hit the surface at the same time. Quote Link to post Share on other sites
