Vectors and Projectiles Module

The Vectors and Projectiles module consists of 10 missions (assignments) that address such topics as vector direction, vector addition, vector resolution, and the horizontal and vertical components of displacement, velocity, acceleration and force for a projectile's motion.  The 10 missions and the corresponding objectives are listed below.  Tap a mission's name to begin.

Mission Objectives:
