With a particle in a conservative force field, the partial derivative of the Lagrangian with respect to velocity is equal to this.
With a particle in a conservative force field, the partial derivative of the Lagrangian with respect to velocity is equal to this. The wavefunction in terms of this quantity can be obtained from the wavefunction in terms of position via a Fourier transform. The quantum mechanical operator for this is equal to negative i times h-bar times the gradient operator. This concept can be used in a ballistic pendulum to calculate a bullet's velocity after it hits a block. The rotational form of this concept can be found as the product of the moment of inertia and rotational velocity. Name this quantity which is classically defined as mass multiplied by velocity.
