  • Conserved quantities under the Lorentz boost - Physics Forums
    The following combination of observables is conserved: ##HR - Pc^2t## where ##H## is the energy, ##R## is the center-of-mass position, and ##P## is the momentum In other words, this means that the center of mass of any system moves with constant velocity along a straight line
  • Is Power Conserved in Energy Systems? - Physics Forums
    As @DrClaude said, power is not conserved, only energy But it is easy to bet confused by the bookkeeping The way to write this is Energystoreddt=Powerin−Powerout If the change in energy stored is zero, then Power In = Power Out If someone is sloppy and forgets to mention stored energy, then it appears that power must be conserved
  • Why momentum is conserved when a gun fires? (conceptual question)
    I understand that conservation of motion comes from the action and reaction pairs of newton's third law When it is triggered, two forces appear that cancel when analyzed as a system My question is how is it that momentum is conserved if before the shot there was no force in the system and afterwards there was
  • Why is Momentum Not Conserved in a Ball of Clay Colliding with a Wall?
    Here we are considering a system of two bodies i e a wall and the clay ball If we consider the motion of the earth, the system will be changed Momentum will be conserved only if there is no external force acting on the system The force may be small or large, tangentially or normally, if it is acting on the system the momentum will not
  • How is Angular Momentum conserved in orbits? - Physics Forums
    I think you caught it later; but back to the top The force quads if the distance halves But the velocity only doubles if the distance halves If the radius doubles then the velocity halves This is linear or arc velocity; and this change in linear velocity is required if angular momentum is to be conserved
  • Conserved charge as a generator of symmetry, Peskin Schroeder
    translational symmery => conserved momentum => momentum operators generate translations rotational symmery => conserved angular momentum => angular momentum operators generate rotations With gauge symmetries it's a bit more invloved since they are local symmetries Look at the Maxwell- or Yang-Mills equations
  • Conservation of Momentum: Falling object - Physics Forums
    Its the total momentum of a closed system that is conserved Not the momentum of a particle In your case the particle has a force acting on it and as such the momentum changes There is no law of physics which states that the momentum of a particle is conserved The gravitational force changs the momentum of a ball in free-fall
  • How momentum is conserved in an inelastic collision - Physics Forums
    These interactions that lose energy to the surroundings will keep energy from being conserved in the system They also violate the concept of “no external forces” and can keep momentum from being conserved When we say momentum and energy are conserved we are claiming we have made all of the external interactions negligibly small
  • Merry-go-round = gt; what is conserved? - Physics Forums
    It's an inelastic collision, so there's goes thinking kinetic energy would be conserved For linear momentum, when the boy contacts the rim of the go-round there is a force coming from the hub that resists the linear motion, but not the angular momentum I think your choice of angular momentum only would be the correct answer
