will two objects of different masses dropped with same force from the same height reach ground on same time.?

Answer 1

Well, your question is not too clear, and the answer depends on what you mean.

The way this question is normally asked, the objects are simply dropped (not "dropped with the same force"), and air resistance is ignored. In that case, the answer is yes, they will hit the ground at the same time. They start out at zero velocity and accelerate at the same rate.

But instead you say that they are "dropped with the same force", which is a bit of a contradiction. If you apply a force to an object as you drop it, you're actually just throwing it, not dropping it. And the act of throwing accelerates the object so that it leaves your hand with some velocity as you let go of it. So then, these objects "dropped with the same force" would start out with non-zero velocities, and the velocities must be different since they are accelerated in your hand at different rates (recall a = F / m). And if these objects are starting off with different velocities, then they will not hit the ground at the same time.

Answer 2

Two objects of different masses will only reach the ground at the same time if released at the same height and same time when in vaccum.This is because the acceleration due to gravity of every falling object is the same.Most of the time,objects appears to fall and reach the ground at different times because of the friction between the surface of the object and the air particles in the air.This caused resistance to the object.

Answer 3

If air resistance is negligible, the objects hit the ground at the same time. If air resistance is significant, then you need to supply more information such as the shapes and surface areas of the 2 objects. E.g the 10kg object might be an iron ball and the 50kg object might be child with a parachute. See link.

Answer 4

In a vacuum, yes. But when you drop them through an atmosphere, atmospheric resistence takes effect, so the shape of the object becomes a factor.

Answer 5

If you disregard air resistance, yes.
If you don't, then probably not.
So theoretically, in a vacuum, bodies of equal mass accelerate at the same rate. On Earth, consider the case of a paratrooper whose 'chute opens and a paratrooper of the same mass whose 'chute doesn't open...

Answer 6

Yes if they are dopped in VACUUM.
IN air the time depends on shape and mass(resistance of air)

Answer 7

yes they will if u ignore the air resistance

Answer 8

yes
