#Codecademy Project 2 = Getting Ready for Physics Class

#PART 1 - TURN up the Temperature

train_mass = 22680
train_acceleration = 10
train_distance = 100
bomb_mass = 1

#Step 1 - Write a function called f_to_c that takes an input f_temp, a temperature in Fahrenheit, and converts it to c_temp, that temperature in Celsius. It should then return c_temp. The equation you should use is: Temp (C) = (Temp (F) - 32) * 5/9
def f_to_c(f_temp):
    c_temp = ((f_temp-32) * 5/9);
    return c_temp

#Step 2 - Let's test your function with a value of 100 Fahrenheit. Define a variable f100_in_celsius and set it equal to the value of f_to_c with 100 as an input
f100_in_celsius = f_to_c(100);
print(f100_in_celsius);

#Step 3 - Write a function called c_to_f that takes an input c_temp, a temperature in Celsius, and converts it to f_temp, that temperature in Fahrenheit. It shoudl then return f_temp. Equation is = [Temp(F) = Temp (C) *(9/5) + 32]
def c_to_f(c_temp):
    f_temp = (c_temp*(9/5) +32);
    return f_temp;

#Step 4 - Let's test your function with a value of 0 Celsius. Define a variable c0_in_fahrenheit and set it equal to the value of c_to_f with 0 as an input
c0_in_fahrenheit = c_to_f(0);
print(c0_in_fahrenheit);

#PART 2 - USE THE FORCE

#Step 5 - Define a function called get_force that takes in mass and acceleration. It should return mass multiplied by acceleration
def get_force(mass, acceleration):
    return(mass*acceleration);

#Step 6 - Test get_force by calling it with variables train_mass and train_acceleration. Save the result to a variable called train_force and print it out
train_force = get_force(train_mass,train_acceleration);
print(train_force);

#Step 7 - print the string "The GE train supplies X Newtons of force.", with x replaced by train_force.
print("The GE train supplies " + str(train_force) + " Newtons of force.");

#Step 8 - Define a function called get_energy that takes in mass and c. c is a constant that is usually set to the speed of light, which is roughly 3 x 10^8. Set c to have a default value of 3*10**8. get_energy should return mass multiplied by c squared.
def get_energy(mass, c=3*10**8):
    return(mass*c**2);

#Step 9 - Test get_energy by using it on bomb_mass, with the default value of c. Save the result to a variable called bomb_energy.
bomb_energy = get_energy(bomb_mass);

#Step 10 - Print the string “A 1kg bomb supplies X Joules.”, with X replaced by bomb_energy.
print("A 1kg bomb supplies " + str(bomb_energy) + " Joules.");

#PART 3 - DO THE WORK

#Step 11 - Define a final function called get_work that takes in mass, acceleration, and distance. Work is defined as force multiplied by distance. First, get the force using get_force, then multiply that by distance. Return the result.
def get_work(mass, acceleration, distance):
    return(get_force(mass, acceleration)*distance)

#Step 12 - Test get_work by using it on train_mass, train_acceleration, and train_distance. Save the result to a variable called train_work.
train_work = get_work(train_mass, train_acceleration, train_distance);

#Step 13 - Print the string "The GE train does X Joules of work over Y meters.", with X replaced with train_work and Y replaced with train_distance.
print("The GE train does " + str(train_work) + " Joules of work over " + str(train_distance) + " meters.")
