Do all objects fall at the same speed?

Answer 1

Ignoring wind resistance, all objects fall at the same speed while under the influence of the same gravitational forces. For example, an object on the moon falls slower than on the earth. But while on the earth, two objects of the same wind resistance will always fall at the same speed. (Example: If you drop a Bowling ball that has no holes and a marble from the top of The Empire State Building at precisely the same time, they will hit the ground at precisely the same time.)

All objects fall at the same speed.

No - aerodynamic objects will fall faster than objects that don't allow air to pass by them easily. Try this with a sheet of paper and a marble. Bottom line - All objects do NOT fall at the same speed

Yes- All objects fall at the same speed: The speed of gravity on earth which is 9.81 m/s^2. The issue here is air resistance. Yes a marble will fall faster than a piece of paper when air resistance is taken into consideration. But if you were to drop both these items at the same time while in a vacuum, then the objects would fall at the same rate. Also, as a note, "speed" is an incorrect word use here. "Velocity" would be more accurate because velocity includes direction as well as a speed, the direction in this case being "down" or "towards the center of the earth".

Above is true but to be practical the stuff we drop is not in a vacuum and therefore falls at different velocities

-Different velocities yes, but at the same acceleration. Just to remove confusion on the issue.no the all do not fall At the same speed but certain objects do.

Answer 2

No. If there were no air resistance, then yes, however the air resistance will differentiate the speeds of objects of different densities and shapes. Think about this --> if you drop a piece of paper, will it go as fast as dropping a bowling ball?

just an add on, this answer is correct and a good way to test it is to take a book and a peice of paper, drop them individually and they fall at different speeds because the book is heavier and with gravity the air resistence is less effective on the book. the paper floats slowly because of the lack of weight and the effect of air resistence. now take the peice of paper, place it on top of the book(like on against the other) and drop them both, the paper should fall at the exact speed that the book falls, the reason being that the book basically takes away all of the air resistence below the paper. gotta love physics class.

Answer 3

Heavier objects and lighter ones do fall at the same speed.

However, aeordynamic objects will fall faster than objects that don't allow air to pass by them easily. Try this with a sheet of paper and a marble.

Answer 4

In the absence of air resistance, all objects fall at the same rate regardless of their mass. This is known as the equivalence principle and was famously demonstrated by Galileo when he dropped two objects of different masses from the Leaning Tower of Pisa.

Answer 5

Yes they do in a vacuum however you have to keep air resistance to the object in mind if it is not in a vacuum. For instance. if you were to drop a feather and a tiny piece of metal both weighing the same at the same time in the air the metal would hit the ground first. However if you were to do the same thing in a vacuum (that is a place where there is no air) they would both hit the deck at exactly the same time.

The Roman, Titus Lucretius (99BC-55BC), wrote in his poem "On the Nature of Things" ( De Rerum Natura ) about objects falling at the same rate in a void. This would seem to be a precursor to Sir Isaac newton's concepts. :

...But the void has no power of resisting anything

at any time whatsoever or at any place;

Its nature is to give way, and so it does.

It follows that the void is passive and everything falls

through it at equal speed whatever its weight..."

Answer 6

Yes, except objects with natural wind-resistance like a piece of loose leaf. But because of gravity all non air-resistant objects are brought down at the same speed.

but No. If there were no air resistance, then yes, the air resistance will differentiate the speeds of objects of different densities and shapes. Think about this if you drop a piece of paper, will it go as fast as dropping a Volly-ball?

No

This is a good way to test it is to take a book and a peice of paper, drop them individually and they fall at different speeds because the book is heavier and with gravity the air resistence is less effective on the book. the paper floats slowly because of the lack of weight and the effect of air resistence. now take the peice of paper, place it on top of the book(like on against the other) and drop them both, the paper should fall at the exact speed that the book falls, the reason being that the book basically takes away all of the air resistence below the paper.

Answer 7

No.

Gravity applies the same force per unit of mass on all objects. With no other forces applied to objects, all would accelerate at the same rate and all would fall to Earth at the same speeds from a given height.

However, as soon as any object starts to fall, its progress is impeded by air resistance. This reduces the velocity of an falling object with less dense and less aerodynamic bodies being reduced more than denser and more aerodynamic bodies. For that reason, feathers fall to Earth far slower and lumps of metal for example.

Answer 8

no. eventhough the time doesnot depend on the mass of the bodies, the shape and size of the body cause different air resistance which resists the motion.

Answer 9

no all objects fall at the same speed if they are in a vacuum the only thing that makes a difference if atmosphere or air.

Answer 10

No. Due to air resistance, some will fall slower than others.
