SUMMARY
The relativistic momentum is defined by the equation p = mvγ, where γ (the Lorentz factor) accounts for the effects of relativity at high velocities. The discussion clarifies that while some physicists prefer using invariant rest mass (m₀), the relativistic mass (mᵣ = γm₀) is also valid for calculating momentum at relativistic speeds. Both approaches are acceptable, and the choice depends on the context and preference of the physicist. Key texts on relativity provide further insights into these concepts.
