It's maybe the most famous scientific experiment, Galileo Galilei's dropping objects from the leaning tower of Pisa in order to prove that all objects fall at the same rate, whatever their mass.In his Two New Sciences (1634) Galileo discusses the mathematics (first to apply mathematics for physics analysis) of a simple type of motion what we call today uniform acceleration or constant acceleration. Then he proposes that heavy bodies actually fall in just that way and that if it was possible to create a vacuum, any two falling bodies would travel the same distance in the same time. On the basis of this proposal, he predicts about balls rolling down an inclined plane, Finally, he describes some inclined plane experiments corroborating his theory.Galileo used inclined planes for his experiment to slow the acceleration enough so that the elapsed time could be measured. The ball was allowed to roll a known distance down the ramp, and the time taken for the ball to move the known distance was measured. The time was measured using a water clock.Galileo showed that the motion on an inclined plane had constant acceleration, dependent only on the angle of the plane and not the mass of the rolling body. Galileo then argued that free-fall motion behaved in an analogous fashion because it was possible to describe a free-fall motion as an inclined plane motion with an angle of 90°. Using Newton's laws, we can prove Galileo's theory by decomposing the gravitational force, acting on the rolling balls, into two vectors, one perpendicular to the inclined plane and one parallel to it. http://www.physics.smu.edu/~ryszard/1313fa98/1313-Incline_.PDFFollowing his experiments, Galileo formulated the equation for a falling body or an object moving in uniform acceleration: d=1/2gt2.The is some evidence shows that such experiments were performed by various scientists and experimenters preceding Galileo's work about falling bodies and by this disproving Aristotle's assertion that heavier bodies fall faster than light ones.As early as 1544, the historian Benedetto Varchi referred to actual tests which refuted Aristotle's assertion.In 1576, Giuseppe Moletti, Galileo's predecessor in the chair of mathematics at the university of Padua, reported that bodies of the same material but different weight, as well as bodies of the same volume but different material, dropped from a height arrived at the Earth at the same time.In 1597 Jacopo Mazzoni, of the University of Pisa, reported that he had observed objects falling at the same speed regardless of weight and pieces of an object descending at the same rate as the whole.The most notorious of those is Simon Stevin that in 1586 (3 years before Galileo) reported that different weights fell a given distance in the same time. His experiments, with the help of his friend Jan Cornetts de Groot, were conducted using two lead balls, one being ten times the weight of the other, which he dropped thirty feet from the church tower in Delft. from the sound of the impacts they concluded that the spheres fell with the same speed, not as stated by Aristotle. Stevin is regarded by many as the first one to perform falling bodies experiments.Experiments to demonstrate the phenomenon.1. Hold on the tip of the fingers of different hands a coin and a paper disc about one meter or more above the floor. Drop both of them simultaneously. The coin will reach the floor before the paper disc. From this experiment is possible to conclude mistakenly that heavier objects fall faster.2. Mount the paper disc on the coin and drop them together. Both objects will reach the ground at the same time. The meaning of this experiment is that not the amount of mass causes falling bodies to fall faster or slower but the resistance/friction of air because air resistance is applied here only to the coin and not to the paper disc and by that we can infer that air resistance and not the amount of mass prevented the paper disc from falling faster - the same as the coin.To exclude the possibility that the coin and the disc of paper attract each other you can show that they do not stick together in any position.Experiments are from:Weiss Moshe, Physics by Experimental Demonstrations, vol II, Jerusalem: Rubin Mass, 1968, pp. 208-209

Does lighter objects fall down faster then heavier objects?
No lighter things do not fall faster than heavier things. In a vacuum they will fall at the same speed. Normally the heavier thing will fall down faster because of its weight. Sometimes the lighter thing falls faster depending on the air resistance.
Why would is it that two objects fall at the same rate?
The best way to answer that question is: Because that's the way gravity works. When you think about it, it's really the only way that makes sense. Let's assume that heavy things fall faster, and light things fall slower. Take a heavy thing and a light thing. Tie them together with 3 feet of string, and drop them from a high building. The light thing wants to fall slower, and it holds the heavy thing back. The heavy thing wants to fall faster, and it pulls the light thing ahead. Together, they fall at some speed faster than the light thing alone, but slower than the heavy thing alone. Bu that's crazy. What difference does it make whether they're tied together with string, stuffed in the same bag together, or hooked together with nuts and bolts ? Together, they're even heavier than the heavier thing, but we just said that they're falling slower than the heavier thing would fall alone. It doesn't add up. Heavier things don't fall faster.
Does heavier objects fall faster that light ones?
That depends. 10 lbs. of bricks will fall at the same speed as 10 lbs. of feathers. Meanwhile, a cinderblock will fall far faster than a single feather. If two things are the same weight, they will usually fall at the same speed. If two things are different weights, they will fall at different speeds. ^ This only takes effect when wind resistance is NOT added.
Why do heavier objects fall faster then lighter objects?
Heavier objects have more gravitational pull on them
Do heavier objects fall faster or slower than light one?
Without air resistance, heavier and lighter object fall at the same speed. More precisely, they accelerate at the same speed - near Earth's surface that would be 9.8 meters/second2. If air resistance is significant, heavier objects tend to have less air resistance, compared to their weight, so they will usually fall faster.

How does the mass of a toy car affect how far it will roll before stopping when it rolls down atrack at an incline?
When things are heavier they fall faster. The faster something goes the longer it takes to stop.
What are aristotles three laws of motion?
* Nothing moves unless you push it. * Heavier things fall faster, proportional to their weight. * The speed of fall of a given object depends inversely on the density of what it is falling through.
What was Aristotle's theory about gravity?
aristotle's theiry of gravity was the heavier the object the faster it will fall.
What is an investigation question?
do heavier rocks fall faster than light rockswhy is the sky bluewhich paper towel is betterwhat is the best fertilizer for all plantswhich paper towel is better that is the answer
Why heavier objects fall faster than do lighter objects?
They don't. All objects fall at the same rate of speed because of weight.
