Lesson Plan: Newton’s Second Law of Motion Physics • First Year of Secondary School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to apply Newton’s second law of motion, 𝐹 = 𝑚𝑎, to find the accelerations caused by forces that act in various directions.
Objectives
Students will be able to
- use the formula in all combinations, where can be the resultant of multiple forces acting along a line in the same or opposite directions,
- substitute the value of calculated using into kinematic formulas,
- substitute the value of calculated using kinematic formulas into ,
- substitute the value of determined using kinematic graphs into .
Prerequisites
Students should already be familiar with
- velocity,
- acceleration,
- free-body force diagrams.
Exclusions
Students will not cover
- variable mass bodies,
- Newton’s third law of motion.
