Aristotle, the ancient Greek philosopher, made numerous contributions to the field of physics, particularly in the study of motion. His observations led him to propose that objects fall at a speed proportional to their weight—the heavier the object, the faster it falls. This concept was part of his broader inquiry into the natural tendencies of elements, asserting a downward movement for earthy materials toward the center of the universe, which he believed to be the Earth's center.
Despite Aristotle's influence, his theories on free fall did not go unchallenged. Observations and experiments over time revealed inconsistencies in his ideas, leading to a scientific evolution that significantly altered our understanding of physics. His work laid the foundation for future scientists, such as Galileo, who would later refine the principles of motion and gravity.
Aristotle believed that heavier objects fall faster than lighter ones. This was later disproved by Galileo, who showed that all objects fall at the same rate, regardless of their weight, in the absence of air resistance.
In the absence of resistance, heavier bodies would fall faster than lighter ones in direct proportion to their weight.Aristotle theorized that the speed of an object's fall is directly proportional to i•
Free fall
Motion of a body subject only to gravity
For other uses, see Free fall (disambiguation).
In classical mechanics, free fall is any motion of a body where gravity is the only force acting upon it. A freely falling object may not necessarily be falling down in the vertical direction. If the common definition of the word "fall" is used, an object moving upwards is not considered to be falling, but using scientific definitions, if it is subject to only the force of gravity, it is said to be in free fall. The Moon is thus in free fall around the Earth, though its orbital speed keeps it in very far orbit from the Earth's surface.
In a roughly uniform gravitational field gravity acts on each part of a body approximately equally. When there are no other forces, such as the normal force exerted between a body (e.g. an astronaut in orbit) and its surrounding objects, it will result in the sensation of weightlessness, a condition that also occurs when the gravitational field is weak (such as when far away from any source of gravity).
The term "free fall" is often used more loosely than in the strict sense defined above. Thus, falling through an atmosphere without a deployed parachute, or lifting device, is also often referred to as free fall. The aerodynamic drag fo
