- 2 : Apply Force
- Apply linear force (if off, torque only)
- 4 : Apply Torque
- Apply rotational force (torque - if off, linear only)
- 8 : Orient Locally
- Maintain local relationship with the attached object
- 16 : Ignore Mass
- Impulse is independent of object's mass (impulse is acceleration NOT force)
