MLPmpWriteAccel
Function A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. - Sets the Acceleration A change in velocity over time. Because velocity is a vector, it can change in two ways: a change in magnitude and/or a change in direction. In one dimension, acceleration is the rate at which something speeds up or slows down. However, more generally, acceleration is a vector quantity expressing the change with time of the velocity both in magnitude and in direction.
