# Gravity and centrifugal forces

If you jumped on an orbital/halo.. Would you carry on flying through the air indefinately or does the centrifugal force push you towards the ground even though you are not in any physical contact with the centrifugalised object??

On a planet we're attracted back towards the ground by gravity.. there's no gravity on a orbital/halo

NOT by my dear friend Alex Cretney

Since you were in contact with the spinning object when you jumped you still will have a tangential velocity in addition to the upwards velocity of your jump. This puts you in a straight line trajectory that intersects the inside of the Halo. Since the halo continues to turn while you are in the air, you will intersect the inside surface at almost exactly the same physical spot as you jumped from. From your perspective, it will seem like you jumped straight up and came straight back down.

## 1. What is gravity?

Gravity is the natural force that causes objects with mass to attract each other. It is responsible for keeping planets in orbit around the sun and objects on Earth from floating away into space.

## 2. How does gravity work?

Gravity works by pulling objects towards each other with a force that is proportional to their masses and inversely proportional to the distance between them. This force is known as the gravitational force.

## 3. What is centrifugal force?

Centrifugal force is the apparent outward force that is experienced by an object in circular motion. It is caused by the object's inertia, which tends to keep it moving in a straight line, and the centripetal force, which is directed towards the center of the circular motion.

## 4. How does centrifugal force relate to gravity?

Centrifugal force and gravity are two opposing forces that work together to keep objects in orbit. While gravity pulls objects towards the center of a circular motion, centrifugal force pulls them away from the center. In the case of Earth's orbit around the sun, gravity is stronger than centrifugal force, allowing the Earth to maintain a stable orbit.

## 5. Can centrifugal force cancel out gravity?

No, centrifugal force cannot cancel out gravity. While centrifugal force can counteract gravity in certain situations, such as in a centrifuge, it is not strong enough to completely cancel out gravity. Gravity is a fundamental force that cannot be cancelled out by any other force.
