If two objects of different weight were dropped from the same height would they hit the ground together?

Question

I'm sorry, I realize how elementary this is and I'm pretty sure of the answer but I just need to be positive.

Someone asked a similar question here and the answers were all contradicting, so please answer ONLY factually.

Answer 1

According to Newton, they should hit at the same time, assuming outside factors, such as wind resistance have no effect. Good link in my source below, explaining it in detail.

Answer 2

In a vacuum, yes, they would hit at the same time. In the atmosphere, the will hit at nearly the same time becuse of differences in air resistance. If you had two objects of the same size and shape, but different weights, like a hollow and solid ball, the should hit at the same time becuase the air resistance is the same. This is true becuase, if air resistance is ignored, the only force acting on the object is gravity. Acceleration due to gravity is a constant, so the object's acceleration, and speed if it started from rest, are constant. A heavier object will have a greater force on it, but it also has greater inertia, or resistance to a change in motion, so the speed will be the same.

Answer 3

In a vacuum, yes. It doesn't matter the shape or mass of the object.

In the atmosphere, the shape of the object does matter. You can negate this affect if you use similar objects (tennis ball vs bowling ball) but it will still produce strange results (for example, a sheet of paper will take longer to hit the ground than a tennis ball, because of air resistance)

Answer 4

If air resistance is negligible, the products hit the floor on an identical time. If air resistance is substantial, then you definitely would desire to furnish greater recommendations such through fact the shapes and floor factors of the two products. E.g the 10kg merchandise ought to be an iron ball and the 50kg merchandise ought to be baby with a parachute. See link.

Answer 5

Yes, neglecting air resistance, a car and a penny will both hit the ground at the same time if dropped from the same height.

Answer 6

In a vacuum: yes.
In the earth's atmosphere: only if they are the same size & shape & weight.
Just like someone jumping from an airplane & someone jumping w/ a parachute: the parachute adds weight, but has shape that increases wind resistance.

Answer 7

Go to the Leaning Tower of Pisa, carry two large balls, one of wood and the other of iron. Let them go at the same time, and see what happens. Oh! I'm sorry. Galileo has already done that a few hundred years ago. They landed at the same time (to the extent that he could tell the difference).

Answer 8

yes, they will hit at the same time. If the objects don't have resistance (like a feather or piece of paper-unless the paper is in a ball) gravity pulls on them the same amount

Answer 9

Yes they will if they have similar shapes, ie 2 ball. If you drop a bowling ball and a tennis ball off a building they'll land at the same time.

Answer 10

Theoretically yes, as acceleration due to gravity is the same. However, one must also include things like air resistance, so you would probably not observe them hitting simultaneously.
