An absolutely crucial activity to help students understand breaking vectors into perpendicular components!
This activity has students both graphically and mathematically (using sine/cosine/tangent) determining components of vectors given the angle above or below the horizontal. Students will also determine missing angles and original vectors given the magnitude of the components.
Essential for any course that utilizes two-dimensional problems (force, projectile motion, etc.)
Activities can be completed before instruction in kinematics topics, or worked into existing curriculum.
Correlates with standards and questions on the New York State Regents Exam in Physics. Carefully made distractors in multiple choice questions help to identify students who don't have full understanding of topic. Also aligns strongly with many other standardized test questions on vectors (AP Physics 1/2, SAT II Physics).
