Method: Joules.elastic_potential_energy

Defined in:

lib/joules/energy_work_power.rb

.elastic_potential_energy(spring_constant, extension) ⇒ Float

Calculates the elastic potential energy given spring constant and extension.

Examples:

Joules.elastic_potential_energy(81.75, 2.4) #=> 235.44

Parameters:

• spring_constant (Int, Float) —

  spring_constant >= 0; spring_constant is in newtons per metre

• extension (Int, Float) —

  extension >= 0; extension is in metres

Returns:

• (Float) —

  return value >= 0; return value is in joules
