    The escape velocity (v_e) is the minimum velocity an object must have in order to break free from a planet’s gravitational influence without further propulsion. It is derived from the balance between the object’s kinetic energy and the planet’s gravitational potential energy.

    The formula for escape velocity is:

    v_e = √(2GM / R)

    Where:
    – v_e is the escape velocity,
    – G is the gravitational constant (6.67430 × 10⁻¹¹ m³ kg⁻¹ s⁻²),
    – M is the mass of the planet,
    – R is the radius of the planet.

    From this formula, we can see that escape velocity depends on the mass of the planet (M) in a square root relationship. Specifically, the escape velocity increases with the square root of the mass. This means that for a planet with greater mass, the escape velocity will be higher.

    Example:
    – A planet with a higher mass will have a higher escape velocity.
    – A smaller planet or a planet with lower mass will have a lower escape velocity.

    In summary:
    – Escape velocity is directly proportional to the square root of the mass of the planet.
