The Perfect Speed: Orbital Velocity Explained

Questions: 20 | Attempts: 10 | Last updated: Mar 2, 2026

Sample Question
Which of the following equations represents the orbital velocity (v) of a satellite in a circular orbit around a central mass (M)?

V = (GM/r)^2

V = GM/r^2

V = (GM/r)^(1/2)

V = (Gr/M)^(1/2)

V = GMm/r
