Galileo was correct in his statement that objects in motion tend to stay in motion, but he seemed to believe that inertial motion moved equidistant from the center of the Earth Descartes was the first one to correctly state that an object in motion continues its motion in a straight line

Galileo’s law of free fall states that, in the absence of air resistance, all bodies fall with the same acceleration, independent of their mass This law is an approximation as can be shown by using Newtonian mechanics

Galileo was a troublemaker by nature, while Newton was a good company man (Although perhaps there is some correlation there with writing styles?) But the punchline remains valid: Newtonian publication remains better for your caree

According to legend, Galileo dropped weights off of the Leaning Tower of Pisa, showing that gravity causes objects of different masses to fall with the same acceleration In recent years, researchers have taken to replicating this test in a way that the Italian scientist probably never envisioned — by dropping atom

The very first discovery in fundamental physics, made by Galileo, – the law of free fall – was also the first discovery in physics of gravity It was the starting point for Newton’s law of universal gravitation a few decades later Indeed Galileo ignored rather than reject Kepler’s laws of planetary motio

Einstein argued that gravity isn’t a force at all He described it as a curvature of time and space caused by mass and energy Their math, laid down in 10 equations, explained how gravity could move around objects via a warped reality, accelerating without ever feeling any mysterious Newtonian force

According to the story, Galileo discovered through this experiment that the objects fell with the same acceleration, proving his prediction true, while at the same time disproving Aristotle’s theory of gravity (which states that objects fall at speed proportional to their mass)

Galileo conducted experiments using a ball on an inclined plane to determine the relationship between the time and distance traveled He found that the distance depended on the square of the time and that the velocity increased as the ball moved down the incline

Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance

Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance A feather and brick dropped together Air resistance causes the feather to fall more slowly

Heavier objects fall faster than lighter objects Why some people say it’s true: If a feather and an egg are dropped, then the egg will reach the ground first Why some people say it’s false: Acceleration due to gravity is independent of the mass of the object

The acceleration is constant and equal to the gravitational acceleration g which is 98 meters per square second at sea level on the Earth The weight, size, and shape of the object are not a factor in describing a free fall In a vacuum, a beach ball falls with the same acceleration as an airliner

Actually, gravity is the weakest of the four fundamental forces Ordered from strongest to weakest, the forces are 1) the strong nuclear force, 2) the electromagnetic force, 3) the weak nuclear force, and 4) gravit

Summary: A team of scientists has calculated the strength of the material deep inside the crust of neutron stars and found it to be the strongest known material in the univers

The strong nuclear force, also called the strong nuclear interaction, is the strongest of the four fundamental forces of nature It’s 6 thousand trillion trillion trillion (that’s 39 zeroes after 6!) times stronger than the force of gravity, according to the HyperPhysics websit
