Python - Calculate Escape Velocity From Star/Planet/Black Hole

print ("This program will calculate the Escape Velocity.") # Import the math module so the sqrt() function can be used import math # Escape Velocity Forumula is: velocity = Square Root [(2 * G * M)/R] # G is a constant: 6.67 x 10**-11 # M = mass of the object you are escaping from # R = radius of the object # Function to solve for velocity # Solve for v: enter m (Mass) and r (radius of object) # (G is a constant; 6.67 x 10**-11) # Formula: v = square root [(2 * G * M)/R] # User can enter mass and radius in exponential notation def solveForEscapeVelocity(): print ("Solving for Escape Velocity") print ("Please enter the mass in kilograms in exponential notation: ") massBase = int(input("Please enter the base: ") ) massExponent = int(input("Please enter the exponent: ") ) massWholeNumber = int(input("Please enter the whole number: ") ) massBaseToPower = math.pow(massBase,massExponent) mass = massWholeNumber * massBaseToPower print ("Please enter the radius in meters in exponential notation: ") radiusBase = int(input("Please enter the base: ") ) radiusExponent = int(input("Please enter the exponent: ") ) radiusWholeNumber = int(input("Please enter the whole number: ") ) radiusBaseToPower = math.pow(radiusBase,radiusExponent) radius = radiusWholeNumber * radiusBaseToPower # G is a constant g = (6.67 * (10**-11) ) # Multiply (mass times G times 2)/radius velocityBeforeSquareRoot = (mass * g * 2)/radius # Then take the square root velocity = math.sqrt(velocityBeforeSquareRoot) print("The velocity is:", velocity, "meters per second") continueCalculations = "y" # Check to see if the user wants to continue to calculate Escape Velocity while (continueCalculations=="y"): solveForEscapeVelocity() continueCalculations = input("Would like to do another calculation for the Escape Velocity?
