A great intermediate activity to help students learn how to select the proper equation when tackling linear motion problems! 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!
Students beginning to master the basic motion equations? Then it's time to graduate to multi-step, multi-equation and more complex problems! Following Activities 1-5 (which each only focus on one equation), Activity 6 now requires students to choose from the entire palette of equations used in linear motion.
As the most common problem is students distinguishing between the various types of velocity (average, initial and final), many problems are designed to force them to correctly assign direction in setup, solution or both.
Some questions are 'stepped-out', giving students cues as to which equations to pick along the solution path. Other (more difficult) questions ask for one answer when students need to perform two calculations to solve their work, which forces students to devise the solution path on their own.
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).
- Solve multi-step linear motion problems using the following equations:
- v = d/t
- vf = vi + at
- a = Δv / t
- d = vit + (1/2)at²
- vf² = vi² + 2ad
- vavg = (vi + vf) / 2
- Solve multi-step linear motion problems both with and without cues
- Solve relative motion problems with relative acceleration between two objects
- Correctly accounting for direction in problems
- Using direction in answers, both with and without cues
