2016年8月14日 · The average velocity of a particle during some elapsed time $\Delta t$ is, in words, the constant velocity that gives the same displacement in the same elapsed time. Mathematically, the average velocity is given by $$\mathbf{v}_{avg} = \frac{\Delta \mathbf{r}}{\Delta t}$$

2021年11月28日 · So far the only way I know to get the average velocity is to add the final and initial velocities and divide by 2. Looking through my textbook and searching online I've come up empty so far. so I've come here for some answers.

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. $$\Large\frac{v_f + v_i}{2} = \bar{v}$$ 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.

2022年8月6日 · The direct part of the question (how to calculate average velocity in a time interval when it is exponentially changing) can be answered simply. However, the way the question was formulated requires a few preliminary words about the time dependence of velocity.

2018年10月2日 · Average velocity=(total distance travelled)/(total time taken) this is the correct defination of average velocity $\endgroup$ – reddot Commented Oct 2, 2018 at 13:56

2019年8月12日 · The average velocity of 3 trials IS the average velocity, you should not be getting different answers if you are doing everything correctly. Are you carrying out your multiplications and divisions to enough decimal points? Leaving out slight remainders could change the answers slightly.

What in particular about constant acceleration allows average velocity to be equal to the midpoint of velocity? $^1$: Resnick, Halliday, Krane, Physics (5th ed.), equation 2-7. kinematics

2017年6月22日 · To get the average velocity you need the change in displacement and the time taken for the change. Unless the displacement is zero you cannot find the average velocity without a time being given or in the case of this example, the maximum velocity. If the accelerations are constant the velocity-time graph looks like this.

2018年6月2日 · $\begingroup$ @Artium to truly calculate the average velocity, you need to take the average of all velocities at every instant of time. Thus, the longer intervals of momentary velocity have a higher weight (since they have more "instants" of time). To illustrate, suppose you travel 1 m/s for 1s and then 10 m/s for 1,000s.
