Suppose you were to quickly throw a ball in outer space. Would it slow down as quickly in space, as it does in Earth? Explain why, or why not.

It would never stop until something hit the ball, to slow it down.

Explanation:

This is so because there is no gravitational pull in space.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
