If I'm on an elevator that breaks free and falls down the shaft, can I jump at the last second to avoid getting hurt?
if you drop a feather on and a steel hammer at the same moment, they should hit the ground at the same instant. why doesn't this work for earth? why does it work for the moon? would it work on Phobos, a moon of mars?
What if we have air resistance in the environment? Will there be any differences? Justify your answer by using Newton’s 2nd Law.

It maintains a distance of about 150 m from the satellite. If the shuttle does not correct its distance between itself and the satellite, how long will it take before they touch?

- Earth exerts a gravitational force on the Moon, keeping it in its orbit. The reaction to this force, in the sense of Newton's third law, is:" O the centripetal force on the Moon O the nearly circular orbit of the Moon O the gravitational force on Earth by the Moon O the tides due to the Moonarrow_forwardStand flat-footed next to a wall.
