Creating a Python Program to Calculate Kinetic Energy

To create a computer program in Python that calculates the kinetic energy of an object, we need to follow a few steps. First, we need to understand the formula for kinetic energy:

Kinetic Energy (KE) = 0.5 * mass * velocity^2

Here's how we can implement this formula in Python:

1. Input: We will take input from the user for the mass (m) and velocity (V) of the object. We can use the `input()` function to prompt the user to enter these values. For example:

   mass = float(input("Enter the mass of the object (in kg): "))
   velocity = float(input("Enter the velocity of the object (in m/s): "))
   

Note that we convert the input values to `float` to handle decimal numbers.

2. Calculation: Next, we will calculate the kinetic energy using the formula mentioned above. We can assign the result to a variable called `kinetic_energy`. Here's the code:

   kinetic_energy = 0.5 * mass * velocity**2
   

The `**` operator is used for exponentiation in Python.

3. Output: Finally, we will display the calculated kinetic energy to the user. We can use the `print()` function for this. Here's the code:

   print("The kinetic energy of the object is", kinetic_energy, "Joules.")
   

The output will be displayed in the format: "The kinetic energy of the object is [kinetic_energy] Joules."

Putting it all together, here's the complete Python program:

mass = float(input("Enter the mass of the object (in kg): "))
velocity = float(input("Enter the velocity of the object (in m/s): "))

kinetic_energy = 0.5 * mass * velocity**2

print("The kinetic energy of the object is", kinetic_energy, "Joules.")

Please note that this program assumes the object is moving in a straight line and does not consider any other factors like air resistance.

I hope this helps! Let me know if you have any further questions.
