### Calculating the pressure in a rotating bucket [closed]

By the way, I am not quite convinced that the solution should be $\frac{1}{2}\rho\omega^2r^2$. I think it should be $\rho\omega^2r^2$. Appreciate any help.

### Centrifugal force in a non-inertial reference frame

There is something I don't quite undestand about the role the centrifugal term plays when describing motion in a non-inertial reference frame. In most Classical Mechanics books, you can find similar ...

### Why do we weigh less on equator when centrifugal force isn't a force at all? [duplicate]

Why would we weigh less on equator as the weighing machine measures the force by which we push ground and that should not change if are on equator or poles?

### Solar Oblateness: Understanding the force balance formula and solar radius in arcseconds

I have 2 questions regarding the following exam-style question and solution: Given a solar mass of $M_{\odot}=2.0 × 10^{30}\,$kg, a solar radius of $R_{\odot}=7.0 \times 10^8\,$m and a rotation ...

### Determine force of particle along trajectory [closed]

The problem: I have a trajectory in cartesian plane defined by points. A particle with mass $m$ runs through this trajectory, with a defined initial velocity. At every moment, there is a force $F$ ...

### Baseball In an O'Neil Cylinder

I am trying to understand the physics of a baseball game in a rotating spacecraft such as the O'Neil cylinder seen in the movie Interstellar. Imagine a cylindrical spacecraft of radius $R$ rotating ...

### What exactly causes particles to drift toward the bottom of a tube in a centrifuge?

As I understand, centrifuges can effectively create gravitational fields that are a thousand times stronger than the Earth's. And it is this pseudo-gravitational force that causes particles to sink ...

### Roche lobes in binary star systems

While studying mass transfer in binary star systems, I came across the concept of Roche lobes and the role of the inner Lagrangian point $L_1$, as shown in the adjoining figure. However, I am having ...

### Clarification on circular motion and pseudo-forces [duplicate]

The way i interpret pseudo-forces is that its a mathematical correction that makes the conclusion of the observer in an accelerated frame correct. And I also believe that this "pseudo-force" has no ...

### Artificial gravity on free falling objects

Assume the following scenario: -two objects in constant velocity free fall side by side to each other (imagine two astronauts in orbit) -one of the two astronauts is inside a non rotating ring ...

### Centripetal and Centrifugal acceleration/force [duplicate]

Centripetal force acts towards the centre and necessary to keep an object in circular motion. But centrifugal force is equal to the magnitude of centripetal force and acts in outwards direction and ...

### Advisory speed limits on turns

I was just thinking about why many corners have advisory speed limits that are less than the highway speed limit, does it have to do with centripetal acceleration?

### If I kept a body in a groove on a frictionless circular table, and rotate the table with a constant angular velocity, what will happen to the block? [duplicate]

I have read that it would slide off the table, because apparently in the frame of the table it experiences a centrifugal force outwards, but I can't seem to agree with that logic. In the ground frame ...

### Bicycles are also balanced by gyroscopic effects, right? [duplicate]

I think that the wheels of a bicycle are rotating when it is moving forward, so there must be gyroscopic effect, so the bicycle is balanced by gyroscopic effect to some extent, right?

### Can opposing centripetal forces help us play catch in a space station?

Let's say we are inside a wheel in our brand-new space station, which spins to simulate gravity, using the centrifugal force. We decide to celebrate our ground-breaking success by play catch in space. ...

### Where do we see centrifugal acceleration?

A body in circular motion always possesses centripetal acceleration which is felt by a person sitting at the center of mass. It will not be felt by a person viewing the motion from the ground frame. ...

### Pressure at depth $h$ of a spinning bucket at top of swing

This was a question posed to me some time ago and it has haunted me ever since. Hints and suggestions would be awesome. Say someone is spinning a bucket of water in a vertical circle of radius $r$ ...

### Why $g$-force increase with radius and centrifugal force decreases? [duplicate]

Trying to understand the 2 formulas and the relations between radius. Common sense will tell me that centrifugal force increases while we are on a curve with a short angle , as newtons law formula ...

### Is Upside-down Racing Possible?

Based on the calculations I have done, upside-down racing seems to be possible. But in my mind, and certainly others too, it seems outlandish and impossible. Here is what I have come up with, please ...

### Y the relation among centripetal, centrifugal and gravitational force exerred on the moon is different from an object on the earth surface?

I read that since the earth vid rotating on its axis ,an object on the earth surface experiences a centrifugal force because the object is also moving around the earth's axis.So,that centrifugal force ...

### Is the Olympic running race fair? [closed]

I noticed that the 200-meter sprints are conducted on curved tracks. (See this video: world championship semifinals 2009) Isn't that weird? I mean, just look at the curvatures of each lane! (Source)...

### Difficulty in understanding why a car slips towards outside as seen from inertial frame

While turning on a road, why does a car slip towards outside, if we are observing the car from inertial frame of reference, i.e center?

### Why do the inner tyres of a vehicle rise when taking a turn at high speeds?

When a person cycles at high speed on a turn, his body bends inwards, to raise the horizontal component of the normal reaction to provide the centripetal force for the turn. The more the speed is, ...

### Work associated with pseudo force

In a non inertial frame if I want to apply the Newton's laws of motion one would use the help of pseudo force but in non inertial frame if I try to apply the work energy theorem should I consider the ...
