    Deceleration Drag
AI Thread Summary
The drag of a standard bullet typically ranges from 0.2 to 0.3 lbs at supersonic speeds, influenced by factors such as bullet shape, weight, muzzle velocity, and atmospheric conditions. While an ideal drag coefficient (Cd) is often cited between 0.2 and 0.4, Cd=0.3 is considered typical for standard trajectories. Weather conditions, including air density, temperature, and humidity, significantly impact drag and bullet performance. A higher drag can enhance stability and accuracy over longer distances, but excessive drag may reduce range. Understanding these dynamics is crucial for optimizing bullet performance in varying conditions.

Can anyone tell me the drag of a standard bullet? I realize there are lots of variables affecting this, but what is the ideal amount of drag without considering particulr weather conditions.
 
Physics news on Phys.org
Of course, you correctly mentioned that numerous factors affect the Drag Coefficient. Keeping that in mind, the following NASA site provides some "typical" values you might find useful. Values in the literature generally range from Cd=(0.2) to Cd=(0.4), with Cd=(0.3) somewhat typical for usual trajectory and environmental parameters.

The drag of a standard bullet can vary greatly depending on several factors such as the shape and weight of the bullet, the muzzle velocity, and the atmospheric conditions. However, on average, a standard bullet can experience a drag force of around 0.2 to 0.3 lbs at supersonic speeds. This drag force increases as the bullet slows down and approaches the speed of sound.

It is difficult to determine an ideal amount of drag without considering specific weather conditions as they play a significant role in the bullet's trajectory and deceleration. Factors such as air density, temperature, and humidity can affect the bullet's drag and ultimately its flight path.

In general, a higher drag force can help stabilize the bullet and improve accuracy, especially at longer distances. However, too much drag can also slow down the bullet and reduce its range. Therefore, it is important to consider the specific weather conditions and adjust the bullet's drag accordingly for optimal performance.
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanged mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
