Question

What two factors act together to keep earth in orbit around the sun

Answer 1

Answer: 2 facts

Explanation: Newton concluded that two factors—inertia and gravity– combine to keep Earth in orbit around the sun, and the moon in orbit around Earth.

Answer 2

Gravity and inertia

Step-by-step explanation:

• Gravity is the force which keeps all the planets in its position. The sun has enough gravity to keep the planets in its orbit.
• Inertia is the force that makes sure that the planets continue to be in motion.
• Gravity and inertia work hand in hand so the planets are in their position and their speed is also maintained.
• If these two forces do not exist, then the earth's orbit would collapse.
