Legend says that newton answered the 2 questions "why do objects fall toward Earth? and What keeps the planets moving in the sky?" by watching an apple fall from a tree. He knew an unbalanced force made it fall, and the same unbalanced force acted on the moon,which keeps it orbiting the Earth. He said these were the SAME force-gravity.
What else can I help you with?
How is the mass of the planet related to the amount of gravity?
Gravity is what keeps the planets orbiting round the Sun instead of disappearing off into outer space. We feel a constant gravity force - our weight - holding us down on the Earth's surface. Isaac Newton was the first one to postulate a gravity force that depends on distance. His idea was a force acting on each planet that varied with the inverse square of the planet's distance from the Sun. He was able to prove that if this was the law of gravity in the solar system, then the planets' orbits must follow Keplers' three laws. Kepler formulated his laws from Tycho Brahe's observations of the planets' positions, but it was many years later that Newton came up with the theory that confirmed these laws. People then realised that Keplers' laws and Newton's laws of motion and the law of gravity were all part of one big theory that all stacked up, and that is what we still believe today.
What was sir Isaac newtons role?
being an epic scientist ~ Sir Isaac Newton made plenty of scientific discoveries- tough the most famous is gravity, he also discovered the Three Universal Laws of Motion, which was then made into basic Physics by him. This helped prove Copernicus's theory of the planets orbiting the Sun. He also made the Binomial Theorem and was one of the two creators of calculus. Ultimately, his discoveries were predecessors to discoveries made by the other great scientists, such as Einstein. -Ben ~
How do you prove newtons third law of motion?
Like any law of physics it is impossible to prove but it can be demonstrated (for example) by placing a brick on a trolley, anchoring the trolley in place with a force metre and pulling the brick in the opposite direction with another force metre. The forces on both meters will be the same
How did newton discover universal law of gravitation?
The law of Gravitation from Newton was ;'' Every matter in the universe attract each other by a line joining them with a forcewhich is directly proportional to the product of there masses and inversely proportional to the square of the distance between there centers.''
What evidence did Galileo use to prove that the Earth revolves around the sun and not the reverse?
Actually he thought was a great idea but he said there was no point in explaining it because the cardinals were all far too dim to understand. Later,discoveries of the law of gravity and the laws of motion were used to show that the Earth must rotate around the Sun in an elliptical orbit. The clincher came in the 19th century with the discovery of stellar parallax for a few of the nearest stars.
Why was newtons laws of motion important?
His laws basically set the core laws for physics. Without them, we would still not know about momentum, gravity, unbalanced forces, etc. They do sound simple, but they helped to prove certain beliefs at that time wrong and invented a whole new world of physics to explore!
Prove that projectile motion is parabola?
The path of a projectile follows a parabolic trajectory because it is influenced by both horizontal and vertical acceleration due to gravity. The horizontal motion is constant and unaffected by gravity, while the vertical motion is uniformly accelerated downward due to gravity. The combination of these two independent motions results in a parabolic path.
How did Newton prove gravity?
Newton prove gravity by means of an apple falling on his head
Which is a characteristic of projectile motion?
One characteristic of projectile motion is that the object follows a curved path under the influence of gravity. This motion can be divided into horizontal and vertical components that are independent of each other. The object’s velocity changes due to the constant acceleration from gravity.
Who was the scientist who did an experiment to prove gravity?
Galileo
How can scientific experiments and observations be used to prove that gravity exists?
Scientific experiments and observations can prove the existence of gravity by demonstrating consistent patterns of motion and interactions between objects in the presence of gravitational forces. By conducting experiments such as dropping objects of different masses and observing their acceleration towards the Earth, scientists can gather evidence that supports the existence of gravity as a fundamental force that attracts objects towards each other. Additionally, observations of celestial bodies in motion, such as planets orbiting around the sun, provide further evidence of the gravitational interactions at play in the universe.

What did glaileo prove when he dropped the orange and the grape?

pluto
