# Hackety Hacking Problem Spring Oscillation Doend

## Problem Statement

Your physics teacher is teaching you the principles of Oscillations. In a demonstration, She shows you how a spring oscillates. After compressing it to 1cm, according to Hooke's Law, which is formulated as F = -K*x , the spring starts oscillating. Write a program which could plot the variation of force with change in length of the spring?

## Sample Output

Please enter the Spring Constant of Spring and press ENTER: 10
The Force at Compressed State = -10 N
The Force at Relaxed State = 0 N
The simulation of Spring motion is as : 0 , 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 9 , 8 , 7 ,6 , 5 , 4 , 3 , 2 , 1 , 0

## Curriculum Connections

To solve this problem, students will:

• Take input from a user
• Store input in a variable
• Understand the usage of Ternary Operator ( and if-else logic)
• Output data to the user
• Demonstrate an understanding of Forces and Laws of Motion

## Solution in RUBY

# This block takes input from the user
puts("Please enter the Spring Constant of spring and press ENTER:")
k=gets.to_i

#count is the integer variable whose value is being incremented
count=0

# Display the Forces at Extreme Positions
puts("\nThe Force at Compressed State = "+(-1*k).to_s)
puts("\nThe Force at relaxed state = 0 N")

# L is the string that accumulates the whole data to be printed
L="The simulation of Spring motion is as :"

# The first loop is the loop used for incrementing the value of count from 0 10
k.times do
L+=count.to_s+" ,"
count+=1
end
# The second loop this is used to vary the value of counting from 10 to 0
k.times do
L+=count.to_s+" ,"
count-=1
end
L+="0"

#Place the output on the screen
puts(L)
