WebFor instance, the motion of an atom has three degrees of freedom (number of ways of absorbing energy), corresponding to the x, y and z components of its momentum. Since these momenta appear quadratically in the kinetic energy, every atom has an average kinetic energy of 3 / 2kBT in thermal equilibrium. WebFeb 1, 2024 · The ratio of their linear momenta would be, P/p=MV/mv. where P and p is linear momentum of first and second body respectively. Substituting for M/m, we get, P/p=v/V. Thus, the ratio of linear momenta of two bodies of differing masses possesing equal kinetic energy is the reciprocal of the ratio of their velocities.

WebJan 21, 2024 · Answer: E₁ > E₂ Explanation: Given, Mass of objects = m₁ and m₂ such that m₁ < m₂ Momentum of the two bodies are equal. Lets assume they are moving with velocity v₁ and v₂ respectively. Thus momentum of first body (P₁)= m₁v₁ and momentum of second body (P₂) = m₂v₂ Since, P₁ = P₂ m₁v₁ = m₂v₂ Given that m₁ < m₂, it is clear that v₁ > v₂. WebJun 29, 2024 · L = m 2 ( r ˙ 2 + r 2 θ ˙ 2 + r 2 sin 2 θ ϕ ˙ 2) − V ( x), which has momenta. p r = m r ˙, p θ = m r 2 θ ˙, p ϕ = m r 2 sin 2 θ ϕ ˙. If you already have the Lagrangian, you can rewrite in Cartesian coordinates, giving the special case Emilio Pisanty discussed. But even if all you knew were the momenta themselves, the ... bird with big neck
