An excellent activity to help students master linear motion problems, specifically targeting on the equation vf² = vi² + 2ad! Field-tested with hundreds of students and years in the classroom, designed to get maximum results with minimum time invested for both student and teacher!
Contained in this activity are 18 questions revolving around the equation vf² = vi² + 2ad. Students will solve for all variables (displacement, acceleration and initial/final velocity) and be exposed to all of the mathematical 'traps' therein, including working with positive and negative numbers.
In my teaching I've found this to be an equation rife with pitfalls. Students forget to square the velocities and can have major issues with order of operations (notably when taking square roots). Also, the absence of proper parenthesis on the calculator can result in errors when squaring the velocities. This problem set is designed to expose students' weakness in these areas (if they exist) to improve their work.
Problems use a wide variety of situations and descriptions to engage students. Multiple choice problems contain distractors designed to capitalize on common student errors.
Correlates with standards and questions on the New York State Regents Exam in Physics. Also aligns strongly with many other standardized test questions in linear motion (AP Physics 1/2, SAT II Physics).
