Ballistics Trajectory

These flashcards cover key concepts related to ballistics and trajectory analysis for forensic investigations.

Ballistics

The science of the motion of projectiles, especially bullets.

Trajectory

The path that a bullet takes through space.

Internal Ballistics

The study of a projectile and the effects of the gunpowder and the barrel on its motion.

External Ballistics

The study of projectile motion after it leaves the barrel until it impacts a target.

Terminal Ballistics

The study of the behavior of a projectile when it is about to hit and as it hits a target.

Entrance Hole

The hole made in a surface when a bullet first penetrates it.

Exit Hole

The hole made in a surface when a bullet exits after penetrating.

Bullet Directionality

The direction from which a bullet impacts a surface.

Parabolic Shape

The trajectory of a bullet which follows a curved path due to gravity.

Elliptical Shape

The shape of a bullet hole created when the bullet strikes at an angle.

Math Calculation of Trajectory

Using the formula sin-1(width/height) to calculate the angle of a bullet's impact.

Point of Origin

The location from which a shooter fires the bullet.

Forensic Ballistics

The application of ballistics to criminal investigations, especially in relation to firearms and bullets.

Protractor

A tool used to measure angles, typically in degrees.

Angle of Impact

The angle at which a bullet strikes a surface, which can change the shape of the hole.

Convergence of Lines

The point where lines representing bullet trajectories meet, indicating the shooter's position.
