  • Angular Momentum
    The rotational equivalent of linear momentum, calculated as the product of moment of inertia and angular velocity.
  • Linear Momentum
    The product of an object's mass and velocity, representing the quantity of motion in a straight line.
  • Moment of Inertia
    The angular equivalent of mass, representing an object's resistance to changes in rotational motion.
  • Angular Velocity
    The rate of change of angular position of a rotating object, measured in radians per second.
  • RPM
    Revolutions Per Minute, a unit of rotational speed indicating the number of full rotations completed in one minute.
  • Axis of Rotation
    The line around which an object rotates, crucial in determining angular momentum.
  • Torque
    A measure of the force that can cause an object to rotate about an axis, similar to angular momentum.
  • Radians
    A unit of angular measure used in angular velocity, where one radian equals the angle made by an arc of a circle.
  • Mass
    A measure of the amount of matter in an object, contributing to both linear and angular momentum.
  • Velocity
    The speed of an object in a particular direction, used in calculating linear momentum.
  • Kilograms
    The SI unit of mass, used in calculating both linear and angular momentum.
  • Meters per Second
    The SI unit of velocity, used in calculating linear momentum.
  • Kilograms Meter Squared
    The unit of moment of inertia, representing mass distribution in rotational motion.
  • Radians per Second
    The unit of angular velocity, indicating how fast an object rotates.
  • Frequency
    The number of occurrences of a repeating event per unit time, used in converting RPM to angular velocity.
