p2 – p1 = p = gh
p
= gh =
1000kg/m3 (9.8m/s2)(4m)
<span>p =
39200 Pa</span>
Gravity adds 9.8 m/s to the downward speed of a falling object every second. (On Earth.)
In 7 seconds, gravity adds (7 x 9.8 m/s) = <em>68.6 m/s</em> to the downward speed of a falling object.
(IF air resistance has no effect on the object.)
