do all objects encounter the same force of gravity as eachother while in a vacuum?

Question

thanks to anyone who answers

Answer 1

Every object that has mass exerts gravity, even you. The earth exerts gravity, hence you are not floating around the room at this moment. The earth and its atmosphere are in a vacume. It not only exerts a pull on you and all thinge terestrial, but also on the moon (which is also in a vacume). The sun exerts a gravitational pull on the earth and all its planets, hence tgey don't shoot off into space. The amount of gravity each object is not influenced by vacumes. The thing that influences the amount of gravity is the mass of the object.

Answer 2

All objects which are at the same distance from the center of earth encounter the force of gravity given by the formula

F = G M m / r^2 .

All points around a circle of radius r from the center of earth, R is constant. G and M are also constants.

Therefore the force is directly proportional to the mass m of the body at that place.

The acceleration at a place is given by F/m = GM/r^2.

On the surface of earth and few kilo meters above the surface of earth we can take r as the radius of the earth and hence we can say the acceleration is constant for few kilometers.

The answer your question is force is proportional to mass and same mass encounters same force.

Answer 3

Please, allow me to clarify some points around here.

Objects in vacumm do NOT fall at a speed of 9.8 m/s.
They are ACCELERATED at a rate of 9.8 m/s2.

Regarding the original question: Gravitational force is proportional to the masses of the objects involved. Thus, the force exerted by earth on a larger object is larger (assuming they are both at the same distance from the center of earth).

Now, precisely as a result of this fact, all objects will fall at the same rate in vacuum.

Answer 4

Yes. In a perfect situation, like a vacuum where there is no air resistance, all objects fall at 9.8 m/s. If you dropped a feather and a penny in a vacuum, they would hit the ground at the same time. Most physics teachers show the demonstration during class.

Answer 5

Not necessarily. The larger objects would exert a greater gravitational pull upon the smaller ones, just like the earth exerts the larger graviational pull on the moon in space.

Answer 6

Not sure I understand your question totally, but if you had two objects on the surface of Earth they would both "feel" the same gravitational force.

Answer 7

I'm no carl sagan, but I would say that the larger the object (such as a planet) the more gravitational force it would have....I hope I understood your question.

Answer 8

Yes !
