9mm (usually called 9mm Luger or 9mm Parabellum) almost always has a higher muzzle velocity than the 380 ACP (also called the 9mm short, 9mm Kurtz, and 9mm Corto). The two bullets are essentially the same diameter however the 9mm Parabellum is almost always a heavier bullet than the 380 ACP with a larger powder charge and a significantly higher chamber pressure.
.30 vs .355
.30 vs. .355
Your acceleration vs. Time graph is the slope of your velocity vs. time graph
Weapon loads at the breech vs. the muzzle.
Weapon loads at the breech vs. the muzzle.
less power vs more power all else being equal.
.355 vs .40
Of course a 45 is more powerful, but the 9mm has the advantage of speed and a larger chamber. If you only get one shot, pick 44. Multipule. Then pick 9mm
Yes it does. Velocity = Displacement / Time. On a graph of displacement vs time, the slope is the velocity. Steeper slope = higher velocity, flatter slope = lower velocity.
Velocity is NOT the slope of the acceleration vs. time graph. Velocity is the area under the acceleration vs. time graph. Velocity is the slope of a position vs. time graph, though. For you Calculus Junkies, v = the integral of acceleration with respect to time.
False. The slope of a velocity vs time graph is acceleration
Velocity=m m=rise/run
