10.4 Projectile Motion Fort Pulaski, GA. One early use of calculus was to study projectile motion. In this section we assume ideal projectile motion:

Unit 6 Notes. Free-Fall: When an object is flying through the air and the only force acting on it is gravity. In our mini-lab with the cannons, we analyzed.

Projectiles (2D) A projectile is any object that is in a state of freefall, or in other words an object that is only acted upon by the force of gravity.

Goal: To projectile motions Objectives: 1)To understand freefall motions in 1 D 2)To understand freefall motions in 2D 3)To understand air drag and terminal.

B2.2.  Projectiles follow curved (parabolic) paths know as trajectories  These paths are the result of two, independent motions  Horizontally, the.
