Galileo's contributions ranges in technology, astronomy, physics and mathematics. Here is a list of his top ones.
He built one of the first telescope, but not designed it (the honour goes to Leonardo DaVinci). He has modified and improved the design.
He observed sunspots and four satellites of Jupiter.
More importantly, he stuck by Copernicus and Kepler to say that the Sun is the center of the solar system, known as the heliocentric or Copernican model. It was commonly believe in his days that the Earth was the centre, known as the geocentric model. This idea dates back to Aristotle, who believe that if the Earth was not in the centre, then the people on Earth would be able to feel the shift, or the wind brushing by, as it rotates.
Galileo was charged with heresy when he revealed the idea in a book. This was mostly because his published Dialogue Concerning the Two Chief World Systems was found offensive to the Cardinal-turned-Pope Urban VIII, as the Pope requested that his ideas be published as part of the writing. However, the writing was a dialogue among three characters, with the pope's ideas being represented bythe dumbest character, "Simplicius" . Hence this led to his arrest.
The study of why objects move is dynamics, whereas the study of how objects move is kinematics.
Static electricity can make objects move by creating an imbalance of positive and negative charges on the surface of the objects. When these charged objects come close to each other, they can be attracted or repelled due to the imbalance of charges, causing movement. This movement occurs as the charges try to equalize and reach a state of equilibrium.
Kinematics as a branch of physics was developed and formalized over time by several scientists including Galileo Galilei, Isaac Newton, and Leonhard Euler. Galileo is often credited with laying the foundation for kinematics by studying the motion of objects and developing the concepts of speed and acceleration.
Friction slows down the motion of objects, so it does not cause them to move faster or fly higher. In fact, more friction can make it harder for objects to reach high speeds or heights.
Static electricity can create forces that cause objects to be attracted or repelled from one another, but it is not typically strong enough to directly move objects on its own. However, in some cases, if the build-up of static charge is large enough, it can cause lightweight objects to move or jump due to the electrical forces involved.
The concept of acceleration was first developed by Galileo Galilei, an Italian scientist, in the 17th century. He studied the motion of objects and formulated the laws of motion that describe how objects move and accelerate.
No
No
Galileo came up with the idea of inertia. Not taking Aristotle's view that an object must have a force acting on it to keep moving, Galileo said that an object would move continuously in a straight line as long as no outside forces acted on it.
The laws of physics.
no he did not!!
-stack objects -make equipment for the US navy -make sushi -sort objects -move heavy objects -massage your back and many more !
On January 7, 1610, Italian astronomer Galileo Galilei discovered, using a homemade telescope, four moons orbiting the planet Jupiter. Looking at what he thought was a group of stars, he realized the objects appeared to move in a regular pattern.
1. an object can move with uniform velocity forever. 2.all objects fall together 3. earth goes around the sun
What do objects snap to when you move them
"Galileo was the first to really discredit Aristotle's laws. He did this by postulating that heavier objects would hit the ground at the same time as lighter objects, when dropped from the same height. He proved this with a famous demonstration where he dropped two balls of different weights from the leaning tower of Pisa. The balls hit the ground at the same time. Galileo also came up with the idea of inertia. Rather than take Aristotle's view that and object must have a force acting on it to keep moving, Galileo said that an object would move continuously in a straight line as long as no outside forces acted on it."
