The Relativistic Momentum calculator computes the momentum (ρ) of a mass (m0) at velocity (v) at relativistic speeds.
INSTRUCTIONS: Choose units and enter the following:
Relativistic Momentum (ρ): The calculator returns the momentum (ρ) in kilogram meters per second (kg•m/s)
The formula foris:
`ρ = (m_0 * v)/sqrt(1 - v^2/c^2)`
This differs from the formula for
Note that in the relativistic equation, as the speed approaches the, the denominator decreases, which has the result of increasing the momentum. Also note that when v is equal to the speed of light, the momentum is infinite, and when v is zero, the equation matches that of
The velocity is restricted to be less than the.
