Figure 36 shows how the average velocity v D x D t v D x D t between two times approaches the instantaneous velocity at t 0. The displacement of the body during this short time interval is given by. Like average velocity instantaneous velocity is a vector with dimension of length per time.

The slope of the position graph is zero at this point and thus the instantaneous.

Instantaneous velocity ms vector change in position m Dt change in time s. The instantaneous velocity of an object is the limit of the average velocity as the elapsed time approaches zero or the derivative of x with respect to t. Instantaneous speed is found by taking the absolute value of instantaneous velocity and it is always positive. After inserting these expressions into the equation for the average velocity and taking the limit as Dt 0 we find the expression for the instantaneous velocity.
