How did newton check his hypothesis that there is an attractive force between earth and the moon?

Answer 1

One fantastically magnificent test he performed was to calculate how planets would

move according to his theory of gravity. He found that if his theory of gravity is

accurate, then planets move according to Kepler's Laws ... written 100 years earlier,

and distilled from Tycho's lifetime of observing and measuring what we actually see

the planets doing in the sky.

Answer 2

Isaac newton there was a force on the moon, because he developed a theory of Equilibrium or law of Inertia. With his Law of Inertia, he could predict that a body will not accelerate or change direction unless operated on by a force. The moon was moving in a curved line , thus there was a force on the moon.

Answer 3

newton calculated how far the circle of the moon's orbit lies below the straight-line distance the moon otherwise would travel in one second.

Answer 4

Has tangential velocity that prevents it from falling into earth

Answer 5

One of the laws of motion that Newton figured out was that an object in motion will tend to stay in motion, IN A STRAIGHT LINE, unless acted on by an outside force.

Answer 6

Maybe he watched the tides and noted the relationship between high tide, low tide and the relative location of the moon.

Answer 7

The Moon, as it orbits the Earth, undergoes an acceleration. In order for there to be an acceleration there must be a force.

Answer 8

Universal gravitation.....
