Relativistic Momentum

The relativistic momentum is the product of the mass and velocity of an object after a Lorentz transformation.

The momentum equals the mass times the velocity divided by the square root of 1 minus the ratio squared of the velocity and the speed of light.

Formula

QuantityVariable["p", "Momentum"] == (QuantityVariable["m", "Mass"]*QuantityVariable["v", "Speed"])/Sqrt[1 + Quantity[-1, "SpeedOfLight"^(-2)]*QuantityVariable["v", "Speed"]^2]
