Question

What theories did Isaac Newton use to describe the motion of the planets? Select all that apply.

periodic motion
laws of motion
law of ellipses
gravity

Answer 1

Answer: laws of motion, gravity

Step-by-step explanation:

They were the only theories that were his.

Sir Isaac Newton, an English mathematician and physicist, developed three laws of motion that helped explain why the planets move the way they do. He also developed the first widely accepted theory of gravity, which also explained why objects in the solar system move the way that they do.

Answer 2

Answer: Newton developed a mathematical formulation of gravity that explained both the motion of a falling apple and that of the planets. He showed that the gravitational force between any two objects is proportional to the product of their masses and inversely proportional to the square of the distance between them.
