Question

Write the formula for the escape velocity of a body from the Earth's surface.​

Answer 1

Answer:

The formula for escape velocity comprises of a constant, G, which we refer to as the universal gravitational constant. The value of it is = 6.673 × 10-11 N . m2 / kg2. The unit for escape velocity is meters per second (m/s).

Answer 2

Escape Velocity and its formula:

Explanation:

• The minimum velocity required by anyone or anything to resist the gravitational pull of the planet earth is referred to as escape velocity. In other terms, escape velocity is the minimum velocity required to escape the gravitational field.
• A constant, G, which we refer to as the universal gravitational constant, is included in the formula for escape velocity. It has a value of =   $6.673\times 10^-^1^1Nm^2/kg^2$.  Meters per second (m/s) is the unit for escape velocity.

        $\textrm{Escape velocity}=\sqrt{\frac{2GM}{R} }$

        Here :

        G  is the universal gravitational constant.

        The mass of the planet or moon is denoted by the letter M. (kg)

        R is the planet's radius in meters.
