Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the key forces in trajectory?Initial velocity, gravitational acceleration, and aerodynamic drag (air resistance)
2. What is the sub-disciplines?Internal ballistics (launch mechanism), external ballistics (flight path), and terminal ballistics (impact)
3. How does a projectile fly through the air?A projectile moves because it is given an initial speed and direction. Gravity pulls it down, making its path curve, while air resistance pushes back against it. The shape, size, and speed of the projectile also affect how it flies.
4. Why did scientists like Galileo study ballistics?Scientists like Galileo wanted to understand the rules that make a projectile follow a curved path. They did experiments and made math models to show that the path is a parabola, which helped later scientists build better weapons and rockets.

Aerodynamic Drag: The resistive force exerted by air on a moving object, dependent on velocity, shape, and air properties.
Trajectory Analysis: The mathematical process of predicting the path of a projectile considering all relevant physical forces.
Terminal Ballistics: The study of the behavior of a projectile and target upon impact.
