Average velocity formula calculus11/8/2023 ![]() For example, an object that moves around a circle with a radius of 50 meters in 13 seconds would have a velocity of 2π(50)m/13s, or approximately 24.17 m/s.Now as we squeeze this window between \(t=1\) and \(t=1+h\) down towards zero, the average velocity becomes the “instantaneous velocity” - just as the slope of the secant line becomes the slope of the tangent line. To do this, use the formula v (velocity) = 2πr (the circumference of the circle)/t (time). The method for finding the velocity of an object around a circle is a little different. In this case, 6m/s + 30m/s divided by 2 = 18 m/s north. To do this, add initial velocity to final velocity and divide the result by 2. Once you know both the final and initial velocity, you can calculate the average velocity of an accelerating object. For example, if an object accelerated north at a rate of 5m/s2 over 5 seconds and had a starting velocity of 6 m/s, its final velocity would be 6m/s + (5m/s2 x 5s), or 31m/s north. If you know the acceleration rate of the object, you can find the final velocity using the formula vf (final velocity) = vi (initial velocity) + a(t) (acceleration x time). If you’re finding the velocity of an object that’s accelerating instead of moving at a constant rate, things get a little more complicated. This will tell you that they ran 30 meters in 5 seconds, which means that they maintained an average velocity of 6 m/s east. Similarly, if they began their sprint at 5:35:01 pm and ended it at 5:35:06 pm, you can find the time by subtracting 1 from 6, giving you 5 seconds. For instance, if a runner began sprinting due east at the 22-meter mark along a track and ended up at the 52-meter mark, you’d subtract 22 from 52 to find the distance, or displacement, of 30 meters. Subtract the initial position from the final position to find distance, and subtract the start time from the end time to find the time. If you don’t already know the time and distance, you’ll need to calculate them first. The most basic formula for calculating velocity is velocity (v) = distance (d)/time (t). The right formula to use for calculating velocity depends on a few different factors, such as whether the object is accelerating at a constant rate, or whether it is moving in a circle as opposed to a line. Velocity is defined as the speed at which an object travels in a given direction. Even though the diver traveled six meters (one up, then five down), what matters is that the end point is four meters below the start point. The diver ended up 4 meters below the starting point, so her displacement is 4 meters downward, or -4 meters. ![]()
