Does initial speed of a gun affect bullet velocity?

AI Thread Summary
The initial speed of a gun can affect bullet velocity, particularly when considering factors like shooting from a moving vehicle or lurching the hand forward while firing. However, the impact on maximum bullet velocity is generally negligible, especially for effective rounds. Even at high speeds, such as 80 mph, the difference in velocity is minimal except for the slowest bullets. Additionally, air resistance can counteract any potential advantages gained from initial speed. Overall, while initial speed has an effect, it is not significant enough to impact the effectiveness of the round.

My brother and I were having an argument so I decided to make an account on this forum. Say you were to lurch you hand forward while firing a pistol. Would that affect the max velocity of the bullet?

It would indeed, just like shooting a gun from a moving vehicle will also affect the velocity of the bullet. The idea is similar to this experiment done by mythbusters:

 
Thanks
 
Would it have an effect on the max velocity of the bullet? yes, but it would be negligible when talking about the effectiveness of the round. Even if you were in a car going 80 mph and shot a bullet directly behind you (or in front of you) it would be negligible in all but the slowest rounds.
 
HA. I remember having this conversation when I was in secondary school ( about 1959). It was about cowboys and rustlers. The question was would the pursuing riders have an advantage of range with their guns over the retreating rustlers. Nothing new under the Sun. :smile:

Rather the opposite, if you consider air resistance.

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...
I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
