- Homework Statement
- Show that the energy momentum relationship E²=p²c² + (mc²)² follows from the expressions E=ymc² and p = ymu
- Relevant Equations
- y = √ (1 - v²/c²) ^-1/2
The textbook says that by squaring and subtracting the expressions you can eliminate u.
E² - p² = y² (mc²)² - y²m²u²
E² - p² = y² (mc²)² - y²m²u²
