Question

How are Newton’s Laws used to describe the motion of planets? Justify your response in two or more complete sentences.

Answer 1

Newton's first law states that every object will remain at rest or in a straight line until it is compelled to change its state by an external force.

Now, touching on the topic of the motion of planets. Planets orbit around the sun and are in motion because of the Sun's gravity.

Answer 2

The answer is: Newton's force of gravity served to explain how the movements of bodies in space work.

Step-by-step explanation:

The theory elaborated by Isaac Newton affirms that this force of attraction, called gravity, is responsible for the fall of the bodies on Earth and the large-scale movements observed in the Universe: the orbit of the Moon around the Earth and the orbit of the planets around the sun.

Newton explained how bodies behave in the face of gravity. From that moment the force of gravity served to explain how the movements of the bodies work on Earth and in space.

The answer is: Newton's force of gravity served to explain how the movements of bodies in space work.
