2 forces keep are the key in earth's orbit: gravity and inertia

Inertia is the bit that would send the earth flying off into outer space, so it can hardly be held part responsible for keeping it in orbit. As the earth tries to speed past the sun (inertia) the attractive gravitational pull force bends it from its path, so it adopts a new direction, and the gravitational force keeps on bending its path and the earth finishes up in an orbit. Much like twirling a weight on a string, where the tension in the string stops the weight from travelling straight on and away. The ancient "sling" weapon used this idea - you twirl the stone in your sling round and round faster and faster, and the tension gets bigger as the rotation gets faster. Then you release your hold and the tension is released and with nothing now to keep it "in orbit" the stone flies off at high speed (due to its "inertia").

A force that keeps planets in orbit?

The force that keeps planets in orbit is gravity. Gravity is the attractive force that exists between two masses, such as a planet and a star, that causes them to be drawn towards each other. In the case of planets orbiting a star, gravity keeps the planets in their elliptical paths around the star.


What force causes planets to orbit the sun in our sloar system?

The sun is a huge mass, 109 times bigger than the Earth. A mass this large has it's own gravitational pull, just as Earth does. The sun pulls all the planets into line so that they can get proper sunlight and life forms on them will not die. so, the cause of the orbiting of the planets is the suns gravitational pull.


What force keeps the moon in orbit around the sun?

The force that keeps the moon in orbit around the sun is the gravitational force between the sun and the moon. This force causes the moon to continuously fall towards the sun but its orbital motion prevents it from colliding with the sun.


What is the driving force that keeps planets orbiting a star?

The driving force that keeps planets orbiting a star is gravity. The star's massive gravitational pull attracts the planets, keeping them in their orbits. Additionally, the planets' own orbital velocity creates a balance between the gravitational pull and their tendency to move in a straight line, resulting in stable orbits around the star. This interplay of gravitational force and motion is described by Kepler's laws of planetary motion and Newton's law of universal gravitation.


What helps keep the planets orbiting the sun?

The planets orbit the sun due to gravitational attraction. The sun's massive gravity pulls the planets towards it, while the planets' tangential velocity allows them to move in a circular or elliptical orbit around the sun. It's essentially a balance between the inward force of gravity and the outward force of the planets' momentum.

What keeps us from floating off into the sky and keeps the planets in orbit around the sun?

Gravity is the force that keeps us grounded on Earth and planets in orbit around the sun. Gravity is a pulling force that attracts objects with mass towards each other. In the case of planets orbiting the sun, the gravitational force from the sun keeps them in their respective orbits.

Does the earth and other planets revolve around the sun?

Yes, the Earth and other planets in our solar system revolve around the Sun in elliptical orbits due to the force of gravity. This orbital motion is what causes the planets to move in their respective paths around the Sun.
