SOLAR SYSTEM

Detailed explanation-1: -Newton concluded that two factors-inertia and gravity– combine to keep Earth in orbit around the sun, and the moon in orbit around Earth.

Detailed explanation-2: -Newton concluded that two factors-inertia and gravity-combine to keep Earth in orbit around the sun and the moon in orbit around Earth. What causes the moon not to move in a straight line around the Earth? The Earth’s gravity pulls the moon inward, preventing it from moving in a straight line.

Detailed explanation-3: -Newton called this force “gravity” and determined that gravitational forces exist between all objects. Using the idea of Gravity, Newton was able to explain the astronomical observations of Kepler.

Detailed explanation-4: -Explain why the Earth orbits the Sun, include both of the terms gravity and inertia in your explanation. Earth has a tendency to resist change, called inertia. Sun’s gravity is constantly pulling on Earth causing it to orbit around the Sun.

Detailed explanation-5: -The gravity of the sun and the planets works together with the inertia to create the orbits and keep them consistent. The gravity pulls the sun and the planets together, while keeping them apart. The inertia provides the tendency to maintain speed and keep moving.
