To find acceleration, we take the derivative of the velocity function. The equation s 16t2 + 128t + 144 gives the height s of the ball t. For a given period of time, the average velocity is defined to be the ratio of the. Height is position (s), use given equation Average velocity is s/t (this is the only and plug in given time for t. To find velocity, we take the derivative of the original position equation. The instantaneous velocity of any object is the limit of the average velocity as. Calculus I: Understanding the Concept of Rate of Change. Chapter 10 - VELOCITY, ACCELERATION and CALCULUS 220 0.5 1 1.5 2 t 20 40 60 80 100 s 0.45 0.55 t 12.9094 18.5281 s Figure 10.1:3: A microscopic view of distance Velocity and the First Derivative Physicists make an important distinction between speed and velocity. We can interpret this equation by saying that the slope m m measures the change in y. Next, decide in which direction (left or right) the particle is moving when ?t=1? and whether its velocity and speed are increasing or decreasing. Calculating and Interpreting the Slope of a Line. Now explore some average velocities in tabular form.Suppose a particle is moving along the ?x?-axis so that its position at time ?t? is given by the formulaĬompute its velocity and acceleration as functions of ?t?. return one of the following three items: the equation of the tangent line, the slope of the tangent line. where y0 is the location of the object when t. Average velocity as the slope of a secant line. Like average velocity, instantaneous velocity is a vector with dimension of length per time. Step 3: Finally, the instantaneous velocity will be displayed in the output field. where the displacement is d and t is the time used to calculate the displacement. 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: v(t) d dtx(t). Step 2: Now click the button Calculate x to get the result.
