So I am making a Delta V calculator. Here it is: https://www.desmos.com/calculator/hib7psndtb
Anyone know how to figure out a rocket's Delta V if it launches from in an atmosphere?
Also, if I messed up on anything (in the Delta V calculator or isp calculator), please let me know so I could...
I am trying to create a spreadsheet that will calculate:
The minimum delta-v required to circularise the orbit of a projectile that has been fired horizontally from the Earths surface at a given velocity.
Completely ignoring atmospheric drag.
See the attached spreadsheet.
The steps are...

I am supposed to find the increase in volume, or more specifically how much mercury will rise inside of a thermometer, given the following values. The volume expansion is 1.8 * 10-4/C(degree Celcius). The temperature increase from 30 to 70 degrees F (already converted the...
Ignoring the fact that the atmospheric friction would probably disintegrate it.
I know that to achieve LEO takes around 10km/s delta v.
But only 2km/s of that is to overcome the drag and gravity.
So you could shoot at 2km/s, get to LEO altitude then it falls back down because it is not at...
Firstly, apologies if this is in the wrong thread.
I'm currently writing a presentation on the physics of getting a spacecraft from Earth to Mars in the near future. In my research I've come up against Porkchop plots which seem to plot contours of equal characteristic energy so you can find...
A satellite changes its orbit inclined 66° at 260.0 km altitude to a polar orbit at the same altitude. What Delta V was required?
... I am stuck.
do I figure it out using:
DeltaV1 = |V_transfer at orbit 1 - V_orbit 1|
and
DeltaV2 = |V_transfer at orbit 2 - V_orbit 2|
or is there another...
How do you calculate how much delta v is lost from gravity and atmospheric drag?
I've been looking for days but I can't find anything that actually tells me how it's calculated.
For example it takes 1.5 km/s - 2 km/s extra delta v for a low Earth orbit because of drag loss, how was that number...
If the velocity of the object of 5 kg changed from 5 m/s to 4 m/s. Then is the change in kinetic energy -22.5 J or +22.5J.
doesn't change mean final velocity minus initial velocity?
I want to calculate the delta V needed to move objects around in a 1-d gravitational field. The relevant equations as far as I can see are the Tsiolkovsky equation,
\Delta V = v_{ex} \ln\left(\frac{m_0}{m_1}\right)
and the equation for calculating escape velocity.
v_e = \sqrt{\frac{2GM}{r}}...
I know delta means change , but I don't what the difference between Δv/Δt vs dv/dt is ?
I am at the noob end of calculus so trying to grasp how to interpret things like dv/dt or what what dv would mean if it were standing alone.
TIA
Greetings everyone!
I have a question on how the delta-V required to reach different orbits is determined. I refer to lift-off delta-V.
I'm curious to find the relationship between altitude and delta V required to get to the height.
From what I have found out, the lift-off delta v to a...
