Objects with three very different sizes and weights are dropped off a tower on the moon. which factor of the objects will determ
1 answer:
4) none of these matter. with no air resistance, they all hit the ground at the same time.
Explanation:
The motion of the objects is a free fall motion, since the only force acting on them is gravity. Therefore, it is a uniformly accelerated motion with constant acceleration (acceleration of gravity) towards the ground, and so we can find the time of flight by using the suvat equation:
where
s is the vertical displacement (equal to height of the tower)
u = 0 is the initial velocity
t is the time
is the acceleration
Re-arranging the equation.
As we can see, the time of flight depends only on the height of the tower (s) and the acceleration due to gravity (g): therefore, the three objects reach the ground at the same time.
