FAQs
What does Gravitational Force calculate?
It computes a key value in gravity & two-body motion using a standard aerospace engineering formula.
Are these results suitable for certification work?
Treat this as a fast estimation tool. Use detailed models and standard references for certification.
Why are results hidden initially?
Results appear only after Calculate so inputs and outputs remain clearly separated.
