Gravity and centrifugal forces

In summary, jumping on an orbital/halo will result in a trajectory that intersects the inside surface of the object due to its continued rotation while you are in the air. This gives the illusion of jumping straight up and coming straight back down.

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.

I can explain that gravity and centrifugal forces are both fundamental forces that act on objects in space. Gravity is the force of attraction between two objects with mass, while centrifugal force is the outward force experienced by an object in circular motion.

If you were to jump on an orbital or halo, you would continue to move in a straight line at a constant speed, as per Newton's first law of motion. However, the centrifugal force would also act on you, pushing you towards the center of the object in a curved path. This is due to the circular motion of the orbital or halo.

Since there is no physical contact between you and the centrifugalized object, the force of gravity would not be present. Therefore, you would not experience the force of gravity pulling you towards the ground. However, the centrifugal force would continue to act on you, causing you to move in a curved path towards the center of the object.

In summary, on an orbital or halo, you would not continue to fly through the air indefinitely due to the presence of the centrifugal force. This force would act on you, causing you to move in a curved path towards the center of the object. However, there would be no force of gravity pulling you towards the ground as there is no physical contact between you and the object.
 

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.
