Anyone know a fast way to calculate Δv?
>>7680660
I like to measure v at one point, then another, and then find the difference of the two using subtraction.

>substraction
Please could you stop using so many complex mathematic buzzwords? I asked for a simple explanation!

Depends on the metric.
v2 - v1

I get a slow motion capture camera and record the object. Then I observe how far the object travels at a instant, for a certain duration of time. Then I take the ratio of how far the object has traveled with regards to how much time has elapsed over a very short interval.
Or I just man the fuck up and learn rudimentary calculus.

Stupid Physicists/Engineers, always approximating.

OP, take your 8th grade physics homework elsewhere.
use a calculator

residue theorem.

subtract the initial velocity from the final one...
>>7680660
Vf-Vi
Where f is final and i is initial, and only considering if your system is path independent.
dv /dx
In what context? Delta V just means change in velocity, it's just a quantity and how you calculate it depends on what you're given. If you're given two velocities, it's final velocity - initial velocity. If you're given an acceleration and a time, just multiply them together. And so on.
Acceleration * Burn Time.
Assuming you throttle for constant acceleration.
You all got trolled, it's a capital V,
the OP wants to calculate potential!
I suggest UNI-T UT58A/B/C digital multimeter;
in the range of 2V - 200V the accuracy of its measurements is +-(0.8%+3dig),
when measuring AC voltage, with resolutions of 1-100mV.

delta v is mathematically defined as v_2 - v_1. there isn't enough additional information to otherwise bring up metrics.
