Special Relativity
Other Math
Explore Einstein's special relativity — time dilation, length contraction, relativistic momentum, and mass-energy equivalence. See how algebra and square roots reveal the surprising geometry of space and time at high speeds.
Learning Objectives
- Understand Einstein's two postulates of special relativity
- Apply the Lorentz factor to time dilation and length contraction problems
- Calculate relativistic momentum and kinetic energy
- Use mass-energy equivalence (E = mc²) to convert between mass and energy
- Solve problems involving relativistic velocity addition
- Interpret spacetime intervals and basic Minkowski diagrams
