What did Galileo discover about motion?

Galileo measured that all bodies accelerate at the same rate regardless of their size or mass. Key among his investigations are: developed the concept of motion in terms of velocity (speed and direction) through the use of inclined planes. developed the idea of force, as a cause for motion.

What did Galileo believe about motion?

Galileo, using an Archimedean model of floating bodies, and later the balance, argues that there is only one principle of motion—heaviness. Bodies move upward not because they have a natural lightness, he says, but because they are displaced or extruded by other heavier bodies moving downward.

How did Galileo discover the law of motion?

Before Galileo it had been thought that all horizontal motion required a direct cause, but Galileo deduced from his experiments that a body in motion would remain in motion unless a force (such as friction) caused it to come to rest. This law is also the first of Isaac Newton’s three laws of motion.

When did Galileo discover motion?

Galileo’s Early Life, Education and Experiments

He left without finishing his degree (yes, Galileo was a college dropout!). In 1583 he made his first important discovery, describing the rules that govern the motion of pendulums.

What are the ideas of Aristotle and Galileo about motion?

Aristotle says that the heavier things are, the quicker they will fall, whereas Galileo felt that the mass of an object made no difference to the speed at which it fell.

How did Galileo’s ideas on motion contradict Aristotle’s ideas on motion?

As we have seen, Galileo’s concept of inertia was quite contrary to Aristotle’s ideas of motion: in Galileo’s dynamics the arrow (with very small frictional forces) continued to fly through the air because of the law of inertia, while a block of wood on a table stopped sliding once the applied force was removed because …

What is Galileo’s famous principle of inertia?

Galileo’s Law of Inertia states that; if no net force acts on an object, the object maintains in the same state of motion. This is a restatement of Newton’s First Law of Motion. The first law of Motion is also known as Galileo’s law of inertia.

What is Galilean motion?

Galilean invariance or Galilean relativity states that the laws of motion are the same in all inertial (or non-accelerating) frames.

What is Galilean horizontal motion?

Beginning on page 244 of Two New Sciences, Galileo gives his classic analysis of the motion of a projectile as a compound motion, made up of a horizontal motion which has steady speed in a fixed direction, and a vertical motion which is his “naturally accelerated motion” picking up velocity in the downward direction at …

What is the view of Galileo in horizontal motion?

Answer. galileo understood that vertical motion does not affect horizontal motion. … Gravity accelerates an object downward even if it is moving horizontally. Galileo was able to show that a projectile is controlled by two independent motions, which work together to create a precise mathematical curve.

What is the result of Galilean relativity experiment?

Galileo actually conducted a similar experiment and discovered that the ball would simply fall directly below where it’s dropped, just as if the ship were stationary. From Galileo’s point of view in the ship’s hull, there was no difference between a ship with constant velocity and a stationary one.

What did Michelson and Morley discover?

The Michelson–Morley experiment was an attempt to detect the existence of the luminiferous aether, a supposed medium permeating space that was thought to be the carrier of light waves.

What is Galilean theory of relativity?

Galileo’s principle of relativity states “It is impossible by mechanical means to say whether we are moving or staying at rest“. If two trains are moving at the same speed in the same direction, then a passenger in either train will not be able to notice that either train is moving.

What is Galilean transformation equation?

They are also called Newtonian transformations because they appear and are valid within Newtonian physics. The Galilean transformation equation relates the coordinates of space and time of two systems that move together relatively at a constant velocity.

Who invented Galilean transformation?

Galilei, Galileo

Galilei, Galileo (1638I).

What is relativistic motion?

relativistic mechanics, science concerned with the motion of bodies whose relative velocities approach the speed of light c, or whose kinetic energies are comparable with the product of their masses m and the square of the velocity of light, or mc².
