Relativistic Momentum

This section is part of the HSC Physic syllabus Module 7: Nature of Light under Light and Special Relativity.

Let’s learn to describe the consequences and applications of relativistic momentum and the limitation on the maximum velocity of a particle imposed by special relativity.

We know the tradition kinematic form of momentum is:

p=mv

Similarly for relativistic momentum:

p = \frac{ mv} {\sqrt{1-\frac{v^2}{c^2}}}   

And after some calculations we can also achieve the momentum and energy equation:

E^2 = (pc)^2 + (mc^2)^2
