This minicourse was prepared for use with secondary physics students in the Dallas Independent School District and is one option in a physics program which provides for the selection of topics on the basis of student career needs and interests. This minicourse was aimed at providing the student with an understanding of the physics of falling objects, projectiles, and missiles. The minicourse was designed for independent student use with close teacher supervision and was developed as an ESEA Title III project. A rationale, behavioral objectives, student activities, and resource packages are included. Student activities and resource packages involve reading about firearm ballistics, free fall, and acceleration, investigating trajectory, analyzing general projectile motion, investigating conservation of momentum and rocket propulsion, and studying blood ballistics.
