Centripetal and centrifual force reactions on objects?

[TitonV]

What would the centripetal and/or centrifual force be, on an object that was traveling in a 10mi circle at 18,000 mi/hr?

OR

how heavy would a person feel riding in a train traveling on the inside of a 10 mi round tube at 18,000 mi/hr?

Welcome to PF.

What formulas do you think apply for centripetal forces?

I can provide an explanation for the concept of centripetal and centrifugal forces and how they would apply to the given scenarios.

Centripetal force is the force that acts towards the center of a circular motion, keeping an object in its circular path. This force is necessary to maintain the object's velocity and prevent it from flying off in a straight line. On the other hand, centrifugal force is the apparent outward force that an object experiences when it is in circular motion. This force is not a real force but rather a perceived force due to the object's inertia wanting to continue in a straight line.

In the first scenario, the object traveling in a 10mi circle at 18,000 mi/hr would experience a centripetal force acting towards the center of the circle. The magnitude of this force can be calculated using the formula F=mv^2/r, where m is the mass of the object, v is its velocity, and r is the radius of the circle. Therefore, the centripetal force on the object would be quite significant due to the high velocity and small radius, potentially causing the object to experience a strong inward pull.

In the second scenario, the person riding in a train traveling on the inside of a 10 mi round tube at 18,000 mi/hr would also experience a centripetal force towards the center of the circle. This force would depend on the person's mass and the radius of the circular motion, which in this case is the radius of the train's path within the tube. The person would also experience a centrifugal force, which would feel like an outward pull due to their inertia. The magnitude of these forces would depend on the person's position within the train and their orientation relative to the circular path.

As for how heavy the person would feel, it would depend on the person's perception. Since the centrifugal force is not a real force, the person would not actually feel any extra weight, but they may perceive a sensation of being pulled outward due to their inertia. This perception may vary depending on the individual's sensitivity to motion and their position within the train.
