Astronomers

The path of the planets about the sun is elliptical in shape, with the center of the sun being located at one focus. (The Law of Ellipses)An imaginary line drawn from the center of the sun to the center of the planet will sweep out equal areas in equal intervals of time. (The Law of Equal Areas)The ratio of the squares of the periods of any two planets is equal to the ratio of the cubes of their average distances from the sun. (The Law of Harmonies)

The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors; in this law the direction of the force vector is the same as the direction of the acceleration vector

Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.For every action there is an equal and opposite reaction

Ptolemy

Ptolemy The theory that the Earth was a stationary sphere that was in the center of the Universe and that the other planets oribted around itPtolemy’s work was considered correct back then and it was accepted by the churchNow all of his theories have been disproven

Coperincus

Copernicus theorized that all the planets were orbiting around the Sun, but the Moon ignored the Sun’s orbit and orbited around the Earth’s orbitHis theory was correct however back then his work was rejected because it went against the belief of the church

Galileo

Galileo was the first one to use a telescope for researchHe saw that the planets were disks, not points of light, as seen through the telescopeThe Moon was not smooth but was covered by mountains and craters“Any two observers moving at constant speed and direction with respect to one another will obtain the same results for all mechanical experiments”

“Any two observers moving at constant speed and direction with respect to one another will obtain the same results for all mechanical experiments”
