What are the explanations of Galileo about motion?


What are the explanations of Galileo 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.

How did Galileo explain uniform motion? Galileo says that at one time he thought a more useful definition would be to use the term uniform acceleration for motion in which speed increased in proportion to the distance traveled, Dd, rather than to the time fit. (In fact, both definitions had been discussed since early in the fourteenth century.)

How does Galileo explain Aristotle’s 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. They concluded that Aristotle was correct and it is the force of gravity that makes this happen.

What is Galileo ratio? “The distances traversed, during equal intervals of time, by a body falling from rest, stand to one another in the same ratio as the odd numbers beginning with unity [namely,1:3:5:7..]”.

When did Galileo discover free fall?

Between 1589 and 1592, the Italian scientist Galileo Galilei (then professor of mathematics at the University of Pisa) is said to have dropped two spheres of different masses from the Leaning Tower of Pisa to demonstrate that their time of descent was independent of their mass, according to a biography by Galileo’s

What are the 7 types of motion?

Rotatory motion, rotatory motion, oscillatory motion, uniform circular and periodic motion, rectilinear motion, oscillatory motion and periodic motion.

What did Galileo say about inertia?

Perhaps Galileo’s greatest contribution to physics was his formulation of the concept of inertia: an object in a state of motion possesses an “inertia” that causes it to remain in that state of motion unless an external force acts on it. Most objects in a state of motion do NOT remain in that state of motion.

What is Aristotle’s theory of motion?

Summary: Basically, Aristotle’s view of motion is “it requires a force to make an object move in an unnatural” manner – or, more simply, “motion requires force” . After all, if you push a book, it moves. When you stop pushing, the book stops moving.

How did Galileo slow down gravity?

Galileo knew that dropping something through water that fell fairly gently did alter the character of the motion, it would land as gently on the bottom dropped from ten feet as it did from two feet, so slowing down the motion by dropping something through water changed things completely.

How did Galileo count time?

Galileo had no stop watch — not even a pendulum clock. Actually, he used a klepsydra, a version of the ancient water clock, which provided a relative measure of distances in terms of amounts of water collected in a jar as the billiard ball rolled down the inclined plane.

How did Galileo calculate gravity?

One of his greatest contributions involved accurately measuring the effect of gravity on free falling bodies. Using a water clock, Galileo measured the time it took for the ball to roll a known distance down the inclined plane.

Will a feather and a brick?

A feather and brick dropped together. Air resistance causes the feather to fall more slowly. If a feather and a brick were dropped together in a vacuum?that is, an area from which all air has been removed? they would fall at the same rate, and hit the ground at the same time.

What did Galileo prove?

He discovered that the sun has sunspots, which appear to be dark in color. Galileo’s discoveries about the Moon, Jupiter’s moons, Venus, and sunspots supported the idea that the Sun – not the Earth – was the center of the Universe, as was commonly believed at the time.

Do heavier objects really fall faster?

Acceleration of Falling Objects

Heavier things have a greater gravitational force AND heavier things have a lower acceleration. It turns out that these two effects exactly cancel to make falling objects have the same acceleration regardless of mass.

How many type of motion are there?

In the world of mechanics, there are four basic types of motion. These four are rotary, oscillating, linear and reciprocating.

What is motion give an example?

motion means displacement or change in the position of an object over time. eg pushing a block is an example of linear motion, opening a door is an example of rotation, rotating stone with attached thread is an example of a circular motion.

What is the law of Galileo?

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.

Why does inertia happen?

All objects resist changes in their state of motion. All objects have this tendency – they have inertia. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.

Did Galileo invent inertia?

The law of inertia was first formulated by Galileo Galilei for horizontal motion on Earth and was later generalized by René Descartes. This law is also the first of Isaac Newton’s three laws of motion.

What are the ideas of Aristotle?

Aristotle’s philosophy stresses biology, instead of mathematics like Plato. He believed the world was made up of individuals (substances) occurring in fixed natural kinds (species). Each individual has built-in patterns of development, which help it grow toward becoming a fully developed individual of its kind.

What are the 4 elements according to Aristotle?

In particular, he believed in four elements: earth, air, fire, and water. Empedocles was a physician as well as a philosopher.

What are the two basic principle of Aristotle’s theory of motion?

Aristotle’s Laws of Motion. Speed is proportional to motive force, and inversely proportional to resistance. Teleology – The 4th and Final Cause — “WHY” is the most important question.

What did Galileo conclude from his experiment?

Galileo concluded that, all other things being equal, the rate of fall of an object is independent of its weight. All objects fall at the same rate in a vacuum and the lunar astronauts demonstrated this on the moon in 1971, dropping a feather and a spanner which hit the ground simultaneously.

What did Galileo find out about pendulums?

Galileo’s discovery was that the period of swing of a pendulum is independent of its amplitude–the arc of the swing–the isochronism of the pendulum. [1] Now this discovery had important implications for the measurement of time intervals. The study of the pendulum, the first harmonic oscillator, date from this period.

Who made the first pendulum clock?

: Christiaan Huygens Patents the First Pendulum Clock. Being bedridden is never much fun, but sometimes it can lead to scientific insight. Such was the case with 17th century Dutch astronomer Christiaan Huygens.
