We learned that if there is no air resistance, objects, no matter how big or small, all fall with the same acceleration due to gravity.
Objects that are dropped always start with an initial velocity of \( 0 \frac{m}{s} \) .
Time of a dropped object
\( \Delta t = \sqrt{ \frac{2 ~~ \Delta \vec{y}}{\vec{a}_g}} ~~~ [s] \)
