Exercise: Gravitational Force

Problem Statement

Gravitational force is the attractive force that exists between two masses. It can be calculated by using the following formula:

$$\dfrac{G Mm}{r^2}$$

where G is the gravitational constant, M and m are the two masses, and r is the distance between them.

You must implement this equation in Python to calculate the gravitational force between Earth and the moon.

Sample Input

G = 6.67 * 10^-11

M_Earth = 6.0 * 10²⁴

m_Moon = 7.34 * 10²²

r = 3.84 * 10⁸

Sample Output

F_G = 1.99 * 10²⁰

Coding Challenge

All the values have already been given to you. You must write the formula in Pythonic syntax and store the answer in the grav_force variable.

If you feel stuck, refer to the solution review in the next lesson.

Good luck!
