Final answer:
Bullets for target shooting are designed to make small holes and are affected by factors such as muzzle velocity, gravity, and air resistance when discussing their trajectory.
Step-by-step explanation:
Bullets used for target shooting usually have spitzer tips or other aerodynamically efficient shapes that make small holes. In Physics, when discussing the trajectory of a bullet, there is often focus on factors like muzzle velocity, the effect of gravity, and air resistance. When a gun is sighted to hit targets at a specific distance, any change in that distance requires an adjustment to account for gravity's pull on the bullet. For example, if a gun is sighted to hit targets 100.0 m away, the bullet will hit lower if aimed directly at a target 150.0 m away. The extent of this drop also depends on the muzzle velocity; a larger muzzle velocity generally means the bullet will travel farther before dropping significantly, assuming no other factors like air resistance are changing. Air resistance slows down the bullet, reducing its range and increasing the amount it drops over a given distance.
