The molecules of a gas or liquid rarely experience perfectly elastic collisions because kinetic energy is exchanged between the molecules'translational motion and their internal degrees of freedom with each collision.

Elastic collisions with the mercury atoms increase the time it takes for an electron to arrive at the grid, but the average kinetic energy of electrons arriving there isn't much affected.

Currently I've set the K . E . conservation equations and the momentum conservation equations equal to each other and have assumed an elastic collision, where L is the Lorentz factor:

To get the answer for an elastic collision, you need to double the target's momentum, and you will then get the correct answer of 0.02 m / s.
45.
To say that the reason the total kinetic energy remains constant is because energy is conserved, followed by saying that energy is conserved because it's an elastic collision, is circular logic.

In a game of relativistic " billiards ", if a stationary particle is hit by a moving particle in an elastic collision, the paths formed by the two afterwards will form an acute angle.
47.
He used momentum, rather than the kinetic energy on which the later established theory is based, as it seemed to him to avoid some difficulties around whether elastic collisions were possible between indivisible atoms.
48.
Collision-induced absorption and emission is distinguished from collisional broadening in spectroscopy in that collisional broadening comes from elastic collisions of molecules, whereas collision-induced absorption and emission is an inherently inelastic process.

:: : Since there aren't any chemical interactions between your shoe and the ball, the transfer of inertia is mediated by the Pauli exclusion principle between electrons in molecular orbitals causing elastic collisions.

Energy is not conserved ( elastic collision of gear wheels is very rare in real life ! ) The change in kinetic energy is just the total kinetic energy before meshing minus the total kinetic energy afterwards.
