Yes, that is correct.
Galileo challenged Aristotle's belief that heavier objects fell faster than lighter ones.
af Example: a hammer falls faster than a feather Galileo: Proved that an objects mass has no effect on its rate of acceleration as it falls. What causes things to fall at different rates here on earth is air resistance.

If the two objects are the same form it will not effect the time that the objects hit the ground. Say for instance you take two balls and fill one up with water and leave the other one, they will both hit the ground at the same time. Assuming that they are the same size.
There were two Until Galileo's experiment, it was widely believed that large objects fell to Earth faster than small ones. That is, it was thought that if two objects of different sizes were dropped from the same height, the larger one would strike the ground first. Galileo showed that not to be the case. But his experiment was extraordinary for another reason. Galileo discredited another Aristotlian idea: that natural phenomena could be explained solely via analysis. Up until Galileo's time, the scientific method had yet to be developed; experimentation was largely unheard of. Proving or disproving a hypothesis via experimentation was not done. Aristotle and his peers believed that natural laws were discovered through discussion and argumentation, and the philosopher who articulated and defended his theories most persuasively was credited with their discovery. Validation through experimentation was not required.He dropped two cannonballs of different masses from the tower and watched them hit the ground at the same time, disproving Aristotle's theory that mass affects the gravity in acted on an object. He proving that mass doesn't matter but air resistance does. But, it was never proved the experiment was done at the leaning tower of Pisa.Debates had started up on one of aristoles laws of nature, that heavier objects fell faster than lighter objects. Galileo wanted to try. He needed to be able to drop the weights from a tall height. The perfect building was The leaning tower of Pisa that was 54 metres tall. He dropped the 2 weights and found out that aristole was wrong. Because the two weights fell at the same time.
the gravity is the same and will fall at the same time. except if the thing is flat, and there will be air resistance so it will go slower to the ground. eg : paper :)) add me on facebook hanifati sabilaa :p

The acceleration is positive.
Aristotle didn't use the word "acceleration," but he did state (incorrectly) that heavier bodies fell faster to the surface of the Earth than did lighter bodies. The poet-philosopher Lucretius MAY have reached a different conclusion, but certainly did no experiments. Writings prior to Galileo Galilei state that Aristotle had been shown to be wrong, but give no details. Dutch scientist Simon Stevin did actual experiments in 1586 with dropped balls and proved conclusively that Aristotle was wrong. However, he also did not use the word "acceleration." Galileo did a mathematical description of balls rolling down a plane, and showed that such bodies experienced constant acceleration. He then speculated that objects falling straight down would do the same. There is no credible evidence that he did any experiments on such objects, as he did not have the instruments to accurately measure their rate of falling.
It goes faster
More massive objects fall faster than less massive objects.
Aristotle formed the theory that objects fall at rates relative to their mass. This is not true. Galileo performed the experiment atop the leaning tower of pisa where he dropped 2 balls of different masses and they fell at the same rate (9.81 m/s/s)
If the two objects are the same form it will not effect the time that the objects hit the ground. Say for instance you take two balls and fill one up with water and leave the other one, they will both hit the ground at the same time. Assuming that they are the same size.
Galileo Galilei found out
As Galileo Galileo was said to have discovered by dropping objects off the Leaning Tower of Pisa, free-falling objects, like a returning bullet, will all travel similarly faster and faster, under the acceleration of gravity (about 9.8 m/s2). Because of the counter-force due to air resistance, objects will stop accelerating, reaching a terminal velocity dependent on their aerodynamic properties. A bullet should reach a terminal velocity of about 200 mph.
Aristotle divided the Universe into two spheres: one above the Moon and the second under it. This enabled him to explain why there is no problem to move objects on the ground and in the air whereas the stars are stable.
The difference is due to inertia. Inertia is the resistance to a change in motion (acceleration). A more massive object will have greater inertia, and therefore a greater resistance to a change in motion, resulting in a slower acceleration. A less massive object has lower inertia, and therefore less of a resistance to a change in motion, resulting in a faster acceleration.
