Bullet Projectile motion Problem

Click For Summary
SUMMARY

The discussion centers on the physics of bullet projectile motion, specifically the independent nature of horizontal and vertical components. It concludes that, in the absence of air resistance, the horizontal velocity remains constant, leading to the assertion that shooting a dart gun at point-blank range does not result in greater damage compared to shooting from a distance. However, the introduction of air resistance alters this dynamic, as a bullet traveling a longer distance experiences reduced impact velocity. Thus, the impact of a projectile is influenced by both distance and air resistance.

Today I had a question from a student that made me think. Maybe I am just over thinking this.

We were discussing the independent nature of horizontal and vertical components of motion. This was done through shooting a dart gun. We came to the conclusion that (without air resistance) the horizontal velocity component of a moving body remains constant.

A student then asked the following question:
"If you shoot something at point blank range, would it do more damage than shot from far away?"

I was puzzled for a moment, but my gut thinks that it should be the same. Am I right?
 
Physics news on Phys.org
well if more damage means higher impact velocity then it depends on the air resistance and the vertical velocity. But the vertical velocity would be almost negligible compared to the horizontal velocity.
 
So...if shot from a completely horizontal position and no air resistance...it would be the same.

With air resistance the bullet that covers a longer distance would have less effect/velocity/impact
