![]() ![]() ![]() That force was air resistance and Galileo claimed that under conditions without air resistance, all objects would accelerate equally. But Galileo reasoned that there was another force at work slowing down the feather. ![]() Of course if you drop a coin and a feather under normal (atmospheric) conditions, the coin will hit the ground first. that a heavy object (a British guinea) and a light object (a feather) will fall at exactly the same rate.This concept of uniform gravitational acceleration was proposed by Galileo Galilei (1564-1642) and directly contradicted the previous claim by Aristotle (384-322 B.C.) that heavier objects fall faster. It shows that the Earth’s gravity accelerates all objects equally, regardless of mass i.e. Use this Free Fall Tube to demonstrate the effects of gravity on items, and help students develop a thorough understanding how gravity works.The Guinea and Feather is one of the most important experiments in classical physics and it is still performed today as a lecture demonstration for thousands of introductory physics students. ![]()
