Method: Joules.time_period_v2

Defined in:
lib/joules/oscillations.rb

.time_period_v2(mass, spring_constant) ⇒ Float

Note:

There are two other methods for calculating time period.

Calculates the time period of a mass-spring system given mass and spring constant.

Examples:

Joules.time_period_v2(20, 5) #=> 12.566370614359172

Parameters:

  • mass (Int, Float) —

    mass >= 0; mass is in kilograms

  • spring_constant (Int, Float) —

    spring_constant > 0; spring_constant is in newtons per metre

Returns:

  • (Float) —

    return value >= 0; return value is in seconds

Raises:

  • (ZeroDivisionError) —

    if spring_constant = 0
