In physics, acceleration is defined as the rate of change of velocity, or as the second derivative of position (with respect to time). It is then a vector quantity with dimension length/time². In SI units, acceleration is measured in meters/second² (ms-2). In other words it is an increase of motion or action.

An apparatus that resists against the leg as you contract your leg towards your body from a wide-leg position to the standing with legs together position. Note: The same apparatus can also be changed to work as an abductor machine by manipulating the position of pins to cause resistance in a different direction.
