Vortex® supports the SI system (International System of Units) also known as the MKS (metre, kilogram, second) system.
Some physical quantities typically used for rigid-body dynamics are shown in the table below:
| Physical Quantity | Unit | Symbol |
|---|---|---|
| Length | Meter | m |
| Mass | Kilogram | kg |
| Time | Second | sec |
| Angle | Radian | rd |
| Linear Speed | Meter per Second | m/sec |
| Linear Acceleration | Meter per Second2 | m/sec2 |
| Angular Speed | Radian per Second | rd/sec |
| Angular Acceleration | Radian per Second2 | rd/sec2 |
| Force | Newton | N |
| Energy | Joule | J |
| Work | Joule | J |
| Power | Watt | W |
| Torque (moment of force) | Newton Meter | Nâ‹…m |
| Moment of Inertia | Kilogram Meter2 | kgâ‹…m2 |
| Spring Constant | Newton per Meter | N/m |
| Spring Damping | Mass per Second | kg/sec |
| Kinetic Loss | Second per Mass | sec/kg |
