Method: Joules.angular_velocity_v1

Defined in:
lib/joules/circular_motion.rb

.angular_velocity_v1(linear_velocity, radius) ⇒ Float

Note:

There is one other method for calculating angular velocity.

Calculates the angular velocity given linear velocity and radius.

Examples:

Joules.angular_velocity_v1(9, 3) #=> 3.0

Parameters:

  • linear_velocity (Int, Float) —

    linear_velocity is in metres per second

  • radius (Int, Float) —

    radius > 0; radius is in metres

Returns:

  • (Float) —

    return value is in radians per second

Raises:

  • (ZeroDivisionError) —

    if radius = 0
