6.4 Gravitational Force

The Problem

Compute gravitational force between two objects.

Hint

The formula for gravitational force is

F = G m^1m^2/r^2

Here G is the gravitational constant. Its value is 6.673*10-11

So, take three input from the users. The mass of the first object, the mass of the second object and the distance between them.

Solution

mass1 = float(input("First mass: "))
mass2 = float(input("Second mass: "))
 
r = float(input("Distance between the objects: "))
 
G = 6.673*(10**-11)
force =(G*mass1*mass2)/(r**2)
 
print("The gravitational force is:", round(force, 5),"N")

Explanation

The calculation is simple. Only two things need to be learned from this.

Have a look, how we wrote 6.673*10-^11

Also, note that while displaying the force, we used a round function. In the round function, we passed the force, the variable we want to display. Then we passed another parameter to tell, how many decimal points we want to display.
