sorry didn't mean to erase the first entry. I just wanted to add.
Aristotle made two assertions and this is one of them:
"Heavier things fall faster, the speed being proportional to the weight"
However, Aristotle was wrong which has been proved by many scientists since.
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

The Greek philosopher Protagoras.
It is said that they did not fall out, but in some myths both eyes were gorged out and buried by Set.
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.
Yes, that is correct.
no, some are heavier therefore fall faster. not! all objects fall at the same rate no matter what size, Galileo said that DUH! both are wrong... partially. Some objects have more air resistance than others. The more air resistance, the slower an object will fall to the ground. ;-) -Th

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.

John said, "The bag was heavier than it looks.""A bowling ball is heavier than a feather."
Who said things go faster as they get nearer to a black hole ? Oh yes ... an objectfalling under the influence of gravitation is accelerated. OK. But no. Things do, butlight is not an object, and it doesn't go faster than 300,000 km/sec .
who said there is friction with air there is a friction called viscosity that exist between each layers of air thus the particle with with higher density will fall faster
He stated that seeing an apple fall made him think about gravitation and why things fall. However he never said it fell on his head.
He basically said that heavier things fall faster. This is not true. Here's a reductio ad absurdum argument to show that it can't be true. Suppose that it IS true. Now drop a 10 pound cannonball and a 20 pound cannonball from the same height. Obviously, the 20 pound cannonball hits the ground first. (Remember, we're assuming Aristotle was right.) Now let's take a string and connect the two cannonballs. The twenty-pound cannonball will fall faster than the ten-pound cannonball ... until they pull the string taut. Now what happens? Does the heavy ball speed the light one up, or does the light ball slow the heavy one down? Do they fall at the average speed of the two? And how do the cannonballs know they're tied together so they know how to fall?
Transport, power, construction. It made advancements in these areas possible by making things faster and easier.
No. Nature is changing when autumn comes, as leaves start falling off trees, things stop or slow down in their growth. Summer is warmer, though you can get warm weather in autumn too. Nature is at its height in terms of things like the leaves are full of life, things are growing faster and so on.
