# how to find average velocity

Be sure to include the direction, like “forward” or “north,” in your answer. Learn more... All you need to calculate average velocity is the total displacement, or change in position, and the total time. For more information on calculating average velocity, including when you have constant acceleration, scroll down! In this problem the initial velocity is 10 mph and the final velocity is 7.5 mph. Calculate v = (v + u) / 2. If you had 3 objects, do the same but divide by 3. v = ds / dt (1) where . If you drove at an average speed or a uniform speed of 55 miles per hour and you had to cover 80 + 30 = 110 miles, this trip took you 2.0 hours. wikiHow's. Velocity is the rate at which an object moves. Your support helps wikiHow to create more in-depth illustrated articles and videos and to share our trusted brand of instructional content with millions of people all over the world. The formula to determine average velocity: Or. How to Calculate Average Velocity Using the definition of the velocity, it can be mathematically expressed as, v found using the above formula is the average velocity VAVG within the time Δt. Please help us continue to provide you with our trusted how-to guides and videos for free by whitelisting wikiHow on your ad blocker. The average velocity calculator solves for the average velocity using the same method as finding the average of any two numbers. The relationship tells us that flow rate is directly proportional to both the magnitude of the average velocity (hereafter referred to as the speed) and the size of a river, pipe, or other conduit. The average speed is 20 m/s / 2 = 10 m/s, because the speed increases from 0 m/s to 20 m/s in a straight line -- in such a case, the average speed is the maximum speed divided by 2. © 2006 -2021CalculatorSoup® Another way to think about it: The formula for average velocity when an object increases from an initial velocity to a final velocity can be determined with the formula below: … Similarly there is a formula in physics that calculates the average velocity from a graph by dividing the sum of the initial and final velocities by 2. v f + v i 2 = v ¯ There is also another formula which calculates the average velocity from a graph by calculating the slope of the line through two points on the graph. This equation seems logical enough. For a car traveling 120m in 5 seconds, what is the average velocity? Seconds * Meters Per Seconds, so in this case: 5 * 20 = 100 The average velocity is the sum of the final and iitial velocity divided by 2. When Δt becomes small (Δt→0), v becomes the instantaneous velocity. The average velocity of a body in a certain time interval is given as the displacement of the body in that time interval divided by time. Average velocity is defined as total displacement/ total time taken for that Given, s = 3t2 −6t So,displacement in between 2s and 5s is s = 3[t2]5 2 − 6[t]5 2 = 3(25 −4) −6(5 −2) = 45m So,average velocity = 45 5− 2 = 15ms−1 Momentum depends on the mass of the body. Follow the instructions listed in the article above. What's the answer to this question? Calculate the average velocity after 5 seconds. Remember that velocity includes speed and direction. Using the formula, we calculate Formula to calculate average velocity. A water balloon is launched upward with an initial velocity of \$40 ft/s\$. To calculate average velocity first we need to find out the net displacement of a given object during the course of its entire motion.
