How is "average velocity" calculated when acceleration is not constant?

Question

delta d over delta t, of course. not thinking.

true Dr D, displacement not total distance, got it

Answer 1

you need a distance figure in place of acceleration

i.e: from point A to Point B how long is the distance
time elapsed

Answer 2

A lot of people are saying total distance / time.

Average velocity = total DISPLACEMENT / time
Integrating the velocity wrt time is simply one way of finding the total displacement.

eg. You move forward 5 m in 1 sec, then backward 3 m in 1 sec.
Total distance = 8m
Total displacement = +2m

Your average speed is 4 m/s,
but average velocity = +1 m/s

Answer 3

To calculate the average velocity, just integrate the velocity over time and then divide by the time elapsed.

Note integrating the velocity over time gives the distance traveled. So you do not need to do the integeration if you know how far the item traveled, just divide the distance by the time elapsed.

Answer 4

Whatever is acceleration, average velocity is the total distance divided by the total time to get to one point to another.

Answer 5

Use the equation V(ave) = (V0 + V1....+Vn)/n

Find the sum of all the values of the velocities and divide them by the number of velocities there are

Alternatively, the equation V = s/t where s is total displacement from the rest position and t is time taken, also applies

Answer 6

If distance traveled and time for travel are known then: r=dt

If not then use an integral calculus function of dt.

Answer 7

by integration with respect to dt
