# Special relativity (Lorentz contraction) Calculator

## Calculates the length contraction of a body moving with some relative velocity with respect to the observer. | ||

- Purpose of use
- I'm trying to create a formula for virtual negative mass at lagrangian points.
- Comment/Request
- Though this is a useful calculator I would also like to see a gravitational time dilation calculator
