By the end of this unit, you will be able to:
Differentiate vector and non-vector quantities
Add & subtract vectors
Find the components of a vector
Solve projectile motion problems using kinematics equations
Separate motion in vertical and horizontal directions
Use mathematical reasoning to identify multiple variables and choose appropriate equations
Over the course of this unit, you will:
Predict where a projectile will land by measuring its starting conditions (position and velocity)
(Time permitting) Experiment to determine the optical launch angle of a projectile
Prerequisite skills: Solving problems using kinematics equations; understanding of position, velocity, and acceleration
