I am somewhat not satisfied with the explanation of accepted answer. I found no mention of normal force which is key to understanding this situation. Also the outward force is centrifugal force, as the frame is rotating. I'll make my point real quick. No banking In this case, normal reaction is orthogonal to centrifugal force, so it has no effect on it. ...

Now, one g is equal to the acceleration due to gravity by Earth on its surface. Force by washing machine is the centrifugal force as clothes try to go along straight path but the resultant provided by the walls of container of machine which provides the required centripetal force. Now, according to Newton's third law of motion , clothes will also give equal ...

The simplest formula for the centrifugal acceleration is $$a = r\omega^2$$ Here, $r$ is the radius which is 0.25 meters in your case. $\omega$ is the angular velocity which is $2\pi$ times the frequency $f$. Your $f$ is 1500 revolutions per minute which is $1500/60=25$ revolutions per second. In the SI units, we have $$a = 0.25\times 4\pi^2 \times 25^2 = ... 0 An astronaut dressed in a magnetic suit inside a room or environment of copper or similar element in characteristics of conductivity or alloy (copper chamber) is a human magnet (magnet man) than will face a force that is opposed to his displacement inside the "chamber". If one of six sides or of all the sides than compose the chamber, one of the sides is the ... 1 You are quite correct that if you have items floating freely inside your space station they won't experience any artifical gravity as the station starts spinning. The artificial gravitational acceleration of an object is a consequence of its tangential velocity v and is given by:$$ g = \frac{v^2}{r}  where $r$ is the distance to the axis. The freely ...

Wait...wait... what? No, no, no, no... No. If a body is spinning, supposing non frictional surfaces and all of that, the energy would not decrease (if there is no external force). The energy is always constant. In that kind of problems there is only rotational energy (there is no other energy): \$ E_{rot}={1\over 2}I\,\omega^2, ...

A pedagogical note: Because students regularly try to look for the centripetal force and get confused (as noted by other answers here), I try to emphasize that it is the acceleration which is centripetal rather than the force (even though the sum is center directed). Because the acceleration is always the result of a sum, I have found that fewer students in ...

You are a bit confused by the meaning of the centripetal and centrifugal force. First, in a reference frame at rest relative to the center of mass, the gravity IS the centripetal force (just because it points towards the center). My impression is that you assumed that there where two forces, gravity and the centrifugal force. Second, in a reference frame in ...

This is a very common "gotcha" for novices, and something that is not covered well at all in textbooks, in my opinion. The problem is one of semantics, not of physics. The term centripetal force does not name a physical force the way gravitational force and electrostatic force do. The words centripetal force stand for the net result of real forces in the ...

Centripetal Force isn't a real force. It is a construct for representing the sum of different forces that cause circular motion. In the case of an orbit, the gravitational force is the centripetal force, which is what you stated in the first equation. They are NOT opposites, as you asked in the question. They do not become arranged to have a net force of ...

After a comment it becomes clear that there is deep misunderstanding here and the question title has nothing to do with the actual problem. Let's get something basic clear: there is no "the centripetal force". That is no force out there that magically decides to come into being when an object moves in a circle. Rather "centripetal" is a label for those ...

Yes, the rotational kinetic energy decreases. The extra energy is converted to thermal energy in the wheel and environment. If you imagine letting the weight go, it will slide across the surface of the wheel as it moves towards the edge. This sliding is motion against friction, so energy is lost there. Then the weight might bang into whatever holds it at ...

The energy is dissipated when the mass stops at the perimeter. Work has to be done to stop the radial motion of the mass.
