What is Movement: Definition and 630 Discussions

The labour movement or labor movement consists of two main wings: the trade union movement (British English) or labor union movement (American English), also called trade unionism or labor unionism on the one hand, and the political labour movement on the other.

The trade union movement consists of the collective organisation of working people developed to represent and campaign for better working conditions and treatment from their employers and, by the implementation of labour and employment laws, from their governments. The standard unit of organisation is the trade union.The political labour movement in many countries includes a political party that represents the interests of employees, often known as a "labour party" or "workers' party". Many individuals and political groups otherwise considered to represent ruling classes may be part of, and active in, the labour movement.The labour movement developed in response to the depredations of industrial capitalism at about the same time as socialism. However, while the goal of the labour movement is to protect and strengthen the interests of labour within capitalism, the goal of socialism is to replace the capitalist system entirely.

    B Coefficient of friction in sea water

    Is there any friction coefficient in the sea as there is in ground? I've tried searching but I see results between 0.4 and 25.7 (?). If there's no such thing as a coefficient of friction to water, how do I calculate the amount of force to start moving a X mass object in water?

    B Does movement affect H2O freezing temperature?

    When water is moving does the actual freezing temperature change or does steam etc not freeze because warmer water keeps getting brought to the surface? Or is there something else going on that lowers the freezing point as long as the water is in motion? There are several reasons for my...

    B Lifespan of a Photon: Debunking the Myth of Time Travel

    The fact that a photon moves only through space (this is what I have read, it can be wrong), not time is said to be the reason why it has so long lifespan, much longer than the calculated lifespan of the universe. Is this wrong? if so, please explain why.

    B How does Earth's rotation affect our movement?

    How is it possible that Earth's rotation doesn't affect our relative velocity? In other words, if I walk in the opposite direction of Earth's rotation, shouldn't I reach destinations faster than if I walk in the same direction? Sorry if the terms are not that accurate, I’m an architect!

    I From what locations do radiated electrons start their movement in Beta decay?

    I know that the Heisenberg Uncertainty principle states that the position of an electron is uncertain, however, if an electron is created due to beta decay, then at what location is it more likely to begin its movement? Is it right inside the proton? Is it the outer edge of the proton? Is it...

    Direction of movement and sign of the charged particle

    From the picture, the particle experiences upwards force. But how to determine the direction of motion? I think there are two possibilities: if the particle is positive, it moves from Q to P and if it is negative it moves from P to Q. Thanks

    A Discretization of diffusion equation of a fluid in movement

    Hello, I want to model the thermal behaviour of a moving heat transfer fluid in 1D, with convective exchanges with the walls. I have obtained the following equation (1 on the figure).

    Question involving clockwise angular movement

    v=1.00*8=>v=8 rad/s ar=>100*8^2=>ar=64 rad/s^2 at=1.00*4=>at=4 rad/s^2 The only question I have is ar=-64 rad/s^2, not 64 rad/s^2 as I calculated. I believe this is because the wheel is accelerating in a clockwise direction. However this is not indicated by the mathematical equation. How do I...

    "New" theory of human movement as described by Tesla. Right?

    Nikola Tesla, the prominent 20th century inventor, stated in his book "My Inventions" that all human movements appear to come from the will but are are actually generated from the outside. He goes on to say that this phenomenon is of incalculable vale to the human race and he urged further study...

    Imagine two electro-magnets about a metre apart aimed at each other. We turn one of them on, and are able to watch the magnetism propagate in slow motion. The moment the magnetism reaches the second electro-magnet, we turn this on (in a manner in which it attracts), and turn the first one...

    Designing a spiral with a certain angle relative to movement direction

The black part is the wall separating the tracks To that end, I've made some calculations, but I have...

    Can I move a macro object at a very small distance (around 10 nm)?

    The Physics of Wheel Movement: Exploring the Dynamics of Torque and Energy

    Why the wheel moves? I intuitively think that it should move to right but I don't really understand why. When AB gets longer by x each end gets longer by x/2 so W goes to right and down. This will create torque and body will move. This explanation seems valid but I can't calculate anything and...

    I Is movement really relative or absolute?

    I was discussing in another page this topic with someone. He said it's relative in everything, meaning that energy and force doesn't count. This is obviously wrong because the fact that today we can't (maybe tomorrow we can) know which thing is moving towards the other and which not, doesn't...

    What did Albert Einstein mean by 'Nothing happens until something moves'?

    Question about direction of movement of water molecule

    When the boat moves to the left, water molecules below it also move to the left. Is it correct to say the reason is because of Newton's 3rd law? Water molecules provide friction force to the boat so force on boat by water molecules is to the right. By Newton's 3rd law, there will be force on...

    Electromagnetism - movement of a coil in a magnetic field

    So my idea was that to reach the equilibrium position, the final moment of force has to be 0 (so in the end the forces will “eliminate” each other). And I found the equation Fm=B*I*l*sinα, which should characterize the force, which affects wire with the current in a magnetic field, and Fleming’s...
