The reason that a heavier object does not fall faster even though there is more gravitational force on it is because it has more mass, and more energy is required to accelerate the greater mass. A small mass doesn't need a lot of force on it to accelerate it. It's "light" in weight. But a heavier one needs more force on it to accelerate it equally. Want a heavier object to accelerate the same as a lighter one? Apply more force. Gravity does that. Automatically. Think it through and it will lock in.

Effect of gravity to falling objects?

The heavy and light objects travel at the same rate because there are two competing factors that cancel each other out. The force of gravity is greater on the heavier object than on the lighter object, proportional to the object's mass. This means that an object with twice the mass will be pulled toward the earth with twice the force. On the other hand, the acceleration is proportional to the force divided by the mass. This means that an object that is twice the mass of another object will be accelerated twice as slowly as the lighter object given the same force. So in order for an object with twice the mass to move at the same rate as the lighter object, the heavier object must be submitted to twice the force. And this is exactly what the force of gravity does. For more information on gravity and forces, you might try the Physics section


What would be the effect on the mass and the weight of an object if the object were taken to a planet with twice the gravity of earth?

the mass would stay the same no matter where you are and the weight is the force of gravity on an object, so depending on the gravity your weight would change


One object has twice as much mass as another object the first object also has twice as much what?

weight = mass * gravity, so as long as the force of gravity is the same on both, an object with twice the mass will weigh twice as much.


Near the earths surface the amount of mass an object has does not affect it's acceleration due to gravity?

That is correct. Earth's gravity, often expressed as 9.8 meters per second square, can also be expressed as the equivalent 9.8 Newton per meter. That is, an object of twice the mass will feel twice the force of attraction from Earth. However, it will also have twice the inertia - it requires twice the force to give it a certain acceleration.That is correct.

the mass would stay the same no matter where you are and the weight is the force of gravity on an object, so depending on the gravity your weight would change

Does something in space need to be spinning to have gravity?

A spinning object does not create gravity. But it does create centripetal forces (also previously known as centrifugal forces) whereby an object traveling the path of a spinning object is propelled toward the outside wall of the spinning object, due to the force angled to the rotation of the circle counteracting the force of the smaller object traveling tangent to its path. The strength of this force is often measured in "G's". A "G" is equivalent to the force of gravity, ie: 2 "G" is equivalent to twice the force of gravity.


Why doesn't a heavier rock fall faster when the force of gravity is twice as much on two kg object verse a one kg object?

Because it takes more force to give a larger mass the same acceleration. So it all balances out ... less force of gravity on a smaller mass, more force of gravity on a larger mass, always produces the same acceleration.


How much force is needed to accelerate an object twice as fast?

You twice it.


If mass creates gravity then why does everything accelerate towards the ground at the same speed regardless of its mass?

F = ma, or rearranged, a = F / m. So while an object with twice the mass feels twice the force due to gravity, that turns out to be precisely the amount of force required to keep the acceleration constant when the mass is doubled.


What would be the effect on the mass and the weight of an object if the object were taken to at planet with twice the gravity of earth?

Nothing would happen to mass, but as weight is technically a force due to gravity, based on mass, the weight would be doubled, but again mass would remain the same.
