Question

Define orbital velocity Derive an expression for it​

Answer 1

Answer:

The expression for orbital velocity is √g( R+h) = √gr. Orbital velocity is the velocity needed to balance the pull of gravity on the satellite with the inertia of the motion of the satellite, the tendency of the satellite to continue

Explanation:

The orbital velocity equation is given by:

1. ⇒v=√GMr.
2. ⇒Fg=GMmr2.
3. ⇒Fc=mv2r.
4. ⇒mv2r.
5. ⇒GMr=v2.
6. ⇒v=±√GMr.

Answer 2

Answer:Orbital velocity : the velocity of the planet in a orbit revolving around the sun is called orbital velocity.

Expression for orbital velocity:

F = GMm/ r²

mv²/r = GMm/r²

V² =GM/r
