Python_Lab_2_Functions An object’s momentum is its mass multiplied by its velocity. The kinetic energy of a moving object is given by the formula

KE=(1/2)mv2, where m is the object’s mass and v is its velocity squared.

Write two functions one for momentum and the other for kinetic energy.

The momentum function must have two required parameters and calculates/prints the object's momentum.

The kinetic energy function must have two required parameters and calculate/print the

kinetic energy.

Write a program that accepts an object’s mass (in kilograms) and velocity (in meters

per second) as inputs and then outputs its momentum and kinetic energy by calling the functions.

Program written in Python

def KEfunction(mass,velocity):

    KE = 0.5 * mass * velocity**2

    print("Kinetic Energy: "+str(KE))

def momentum(mass,velocity):

    P= mass * velocity

    print("Momentum: "+str(P))

Mass = float(input("Mass (kg): "))

Velocity = float(input("Velocity (m/s): "))

KEfunction(Mass,Velocity)

momentum(Mass,Velocity)

Explanation:

This line defines the kinetic energy function

def KEfunction(mass,velocity):

This line calculates the kinetic energy

    KE = 0.5 * mass * velocity**2

This line prints the kinetic energy

    print("Kinetic Energy: "+str(KE))

This line defines the momentum function

def momentum(mass,velocity):

This line calculates the momentum

    P= mass * velocity

This line prints the momentum

    print("Momentum: "+str(P))

The main method begine here

This line prompts user for mass

Mass = float(input("Mass (kg): "))

This line prompts user for velocity

Velocity = float(input("Velocity (m/s): "))

This line calls the kinetic function

KEfunction(Mass,Velocity)

This line calls the momentum function

momentum(Mass,Velocity)
