# Getting-Ready-for-Physics-Class

You are a physics teacher 👨‍🏫 preparing for the upcoming semester. You want to provide your students with some functions that will help them calculate some fundamental physical properties.

Equations to use:

• Temp (C) = (Temp (F) - 32) * 5/9
• Temp (F) = Temp (C) * (9/5) + 32

Given Variables:

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

---

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.

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.

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 should then return f_temp.

4. 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.

5. Define a function called get_force that takes in mass and acceleration. It should return mass multiplied by acceleration.

6. Test get_force by calling it with the variables train_mass and train_acceleration. Save the result to a variable called train_force and print it.

7. Print the string “The GE train supplies X Newtons of force.”, with X replaced by train_force.

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.

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.

10. Print the string “A 1kg bomb supplies X Joules.”, with X replaced by `bomb_energy**.

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.

12. Test get_work by using it on train_mass, train_acceleration, and train_distance. Save the result to a variable called train_work.

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.
