On what factors does orbital velocity depend ?

Explanation

To determine the factors on which orbital velocity depends, we start with the mathematical expression for orbital velocity. The orbital velocity (v₀) of an object in orbit can be expressed using the formula:

\[ v₀ = \sqrt{\frac{GM}{r}} \]

Where:
- \( G \) is the universal gravitational constant.
- \( M \) is the mass of the planet around which the object is revolving.
- \( r \) is the distance from the center of the planet to the object in orbit (which is the sum of the planet's radius and the height of the object above the planet's surface).
