Image result for The planets in our solar system orbit the sun. They do so well in a elongated circular path called ellipse. Is there a net force acting on the planets as they orbit the sun?
Newton realized that the reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.
