What was Galileo thought experiment?

Galileo thought that a ball, rolling or sliding down a hill without friction, would run up to the same height on an opposite hill. Galileo’s conclusion from this thought experiment was that no force is needed to keep an object moving with constant velocity. …

What did Galileo conclude from this experiment?

Galileo concluded that an object moving on a horizontal plane that is frictionless, should move with constant velocity, i.e. it must neither have acceleration nor retardation.

What does Galileo think will happen if you drop a ball from the top of a tall mast on a boat moving at a constant velocity?

In Aristotelian physics a cannonball dropped from the top of a mast of a moving ship will land directly below where it is dropped. The ball lands at the base of the mast no matter how fast or slow the ship is moving. This means that the cannonbal shares the motion of the ship.

Who is believed to be the first people to experiment with sails?

Galileo’s ship refers to two physics experiments, a thought experiment and an actual experiment, by Galileo Galilei, the 16th and 17th century physicist and astronomer.

Did Galileo know about gravity?

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 motion.

How did Galileo prove gravity?

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. As the atoms rose and fell, both varieties accelerated at essentially the same rate, the researchers found.

Can an object round a curve without any force acting upon it?

Explain. [8] Can an object go round a curve without any force acting on it? However, Newton’s 1st Law says that motion at constant velocity requires no force.

Is a satellite above the Earth’s atmosphere in free fall?

Is a satellite circling Earth above the atmosphere in free fall? One at terminal velocity does encounter air resistance and is not in free fall. (b) The only force acting on a satellite is that due to gravity, so a satellite is in free fall (much more about this later).

What was the largest galleon ever built?

São João Baptista
The São João Baptista (English: Saint John the Baptist), commonly known as the Botafogo, was a Portuguese galleon built in the 16th century, around 1530, considered the biggest and most powerful warship in the world by Portuguese, Castillian and Italian observers of the time….São João Baptista (galleon)

Where is LightSail 2 now?

LightSail 2’s average orbital altitude—now roughly 707 kilometers (439 miles)—is slowly decreasing. Though the spacecraft orbits Earth higher than the International Space Station, the planet’s atmosphere is still thick enough to counteract the thrust gained from solar sailing.

What was the purpose of Galileo’s ship Experiment?

Galileo’s ship refers to two physics experiments, a thought experiment and an actual experiment, by Galileo Galilei, the 16th and 17th century physicist and astronomer. The experiments were created to argue the idea of a rotating Earth as opposed to a stationary Earth around which rotated the Sun and planets and stars.

How did Galileo come up with his hypothesis?

Galileo arrived at his hypothesis by a famous thought experiment outlined in his book On Motion. This experiment runs as follows: Imagine two objects, one light and one heavier than the other one, are connected to each other by a string.

How is Galileo’s ship moving at a constant speed?

Galileo’s ship is moving at a constant speed to the left. The fish remains stationary relative to the Earth. Galileo drops a ball at time t1 that hits the ground at time t2. The fish’s position is displayed at both times.

What did Galileo do with the rock he dropped from the mast?

As part of a lengthy 1624 reply, Galileo described the experiment of dropping a rock from the mast of a smoothly moving ship, and observing whether the rock hit at the base of the mast or behind it. Various people had discussed the experiment in theoretical terms, and some claimed to have done it, with conflicting reports as to the result.
