How to Use This Calculator

Enter mass 1 (kg) — e.g., Earth = 5.972e24 kg — and mass 2 (kg) — e.g., a person = 70 kg.
Enter the center-to-center distance (m) between the two masses.
Read gravitational force (N) and the acceleration of mass 2 (m/s2).
Review gravitational potential (J/kg), escape velocity (m/s), and orbital velocity (m/s).
Use orbital period (s) to understand the circular orbit at this distance.
