It was first demonstrated by Galileo that objects fall toward the Earth with a constant acceleration, regardless of their size. He did this by means of experiments using various objects which were rolled down inclined planes. He did not, contrary to popular legend, drop various objects off the Leaning Tower of Pisa.

Without air resistance all objects regardless of their size and mass exp erience the same acceleration of gravity is it true or false?
It's true, it's true! Galileo proved it.
Who proved that acceleration due to gravity is constant?
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.
Who proved that all objects fall to earth at the same speed?
It wasn't a proof, but Galileo put on a pretty convincing demonstration with the objects he allegedly dropped from the top of the leaning tower of Pisa.
How do you calculate grativity?
Gravity is not technically a constant force. Without going into deep detail, Einstein's theories on general relativity predict that the "Gravitational Constant" is not truly a constant, and recent orbital experiments have proved him correct. That all said, we still live in a practical world; Newtonian Physics still is what we use for "normal" calculations, despite the proof that Einsteinian Physics is actually correct. OK, enough deep philosophizing. In Newtonian physics, "gravity" describes the force two objects with mass exert on each other. For any two object with mass, the force of gravity (i.e. attractive force) is described by this equations: F = G (m1 * m2) / r^2 That is, in English: Attractive force is equal to the product of the Gravitational Constant with the product of the masses of the two objects, divided by the square of the distance between the center of mass of each of the two objects. The Gravitational Constant is an empirical value (not like PI, which is merely an irrational numbers), whose actual value has been determined by experimentation and observation. Currently, G is calculated to be 6.67300 × 10-11 m3 kg-1 s-2
Do things fall at the same speed?
Well it really depends on several factors that have to be just right in order for two objects to fall at the same speed or rate.The three main factors needed to calculate the speed at which two objects fall are Time(t) Velocity(v) and Rate of Acceleration.The formula used to calculate is:Acceleration= v-u/t (the v-u is change in velocity)The reason different objects accelerate the same (when you can ignore air resistance!) is because an object with more mass has more weight, but it also has more inertia.

How was the cosmoligical constant proved wrong by Hubble?
Albert Einstein's cosmological constant was proved wrong by Hubble as he proved the universe is expanding so it doesn't need a constant to stop it imploding.
Is the total volume of cloud around the Earth constant?
Yes, but cannot be proved
Who dropped weigts from the top of a tower to prove that ghravity affects everything equally?
Galileo Galilei is reported (see addendum) to have dropped a ten-pound weight and a one-pound weight off the Leaning Tower of Pisa, and proved that both fall at the same speed. Of course, a more general principle was being demonstrated, the fact that objects of any weight fall at the same speed (with the same acceleration, actually). Does this experiment fit the bill? Does it, in fact, prove that objects of any weight fall with the same speed or acceleration?

What is the name of the scientist who proved that gravity causes falling objects to accelerate constantly no matter what the mass of the object may be?
Galileo Galilei
What teddy stallard prove at the end?
He proved that one should not be treated differently from other regardless of how they appear. All should be treated fairly and no different.
What will an object weigh on the Moon's surface if it weighs 100Newtons on Earth's surface?
We know that the weight of any object = the mass of the object* g, [where g is the gravitational acceleration]. For any object the mass will be constant in any case. Though Einstein proved that if any object moves with the velocity greater than light it's mass will increase. But in this case the mass will not change. But the gravitational acceleration will change. It is proved that the gravitational acceleration of moon is 1/6 of the gravitational acceleration of the earth. So, the weight of the object on moon will be 100/6 newton=16.666(apporximately) newtons.
Who helped in the development of pi?
1.Euler 2. Lambert 3.Liouville 4.Hermite 5.Linderman - Euler's infinite Expansion of Pi with primes. - Lamert proved that Pi was irrational - Liouville proves the existence of Transcendental numbers - Hermite proved that the constant was transcendental. - Linderman proved that Pi was trancendental Thanks :)
What is UFO. is it really found?
they are UNIDENTIFIED FLYING OBJECTS. actually these are not proved but reaserches are going on to prove that there are some extra terrestrial objects outside our solar system. some people also have been seen them.so may be they are real.
Which balls falls the fastest a tennis ball or a baseball?
The acceleration of anything, including the four objects listed, completely dependson the force acting on the object.If you were to push on each of those 4 objects with the same force, then thebowling ball would respond with the least rate of acceleration, because its massis the greatest.But if you could come up with sufficient force, you could accelerate the bowling ballfaster than a golf ball off the face of a driver.It is also true that if you drop all 4 balls near the surface of the Earth, they will all fall with the same acceleration. This is known as the acceleration due to gravity, which is approximately 32.2 feet per second per second. According to legend, Galileo proved this by dropping a light ball and a heavy ball off the roof of the Leaning Tower of Pisa. Newton explained this about a century later with his law of gravitational attraction, according to which the weight of an object at a given distance from the center of the Earth is proportional to its mass. Another of his laws says that the acceleration of an object under the action of a force is equal to the force divided by the mass. These 2 laws together prove that all objects at the same distance from the Earth fall with the same acceleration.
