Lesson Plan
Grade: Date: 17/01/2026
Subject: Physics
Lesson Topic: Dynamics An understanding of forces from Cambridge IGCSE/O Level Physics or equivalent is assumed.
Learning Objective/s:
  • Describe displacement, velocity and acceleration and their inter‑relationships.
  • Apply the three equations of motion to solve constant‑acceleration problems.
  • Choose and use consistent sign conventions when analysing dynamics.
  • Derive the third equation of motion from the first two.
  • Analyse real‑world scenarios (free fall, projectile, inclined plane) using the equations.
Materials Needed:
  • Projector and screen
  • Whiteboard and markers
  • Printed worksheet with practice questions
  • Calculators or classroom computers
  • PhET motion simulation app (or similar)
  • Ruler/graph paper for sketching diagrams
 Introduction:
Begin with a quick “think‑pair‑share” on everyday examples of motion to hook interest. Review that students already know force, mass and Newton’s II law, linking these to kinematic variables. State that by the end of the lesson they will be able to select and use the correct equation of motion and justify their sign choices.
Lesson Structure:
  1. Do‑now (5 min): Mini‑whiteboard quiz on definitions of displacement, velocity and acceleration.
  2. Mini‑lecture (10 min): Review kinematic variables, introduce the three equations and sign conventions using projector.
  3. Derivation activity (8 min): Guided pair work to derive \(v^{2}=u^{2}+2as\) from the first two equations.
  4. Demonstration (7 min): Video of a block sliding down an incline; discuss chosen positive direction and identify variables.
  5. Worked example (10 min): Solve the car‑acceleration problem step‑by‑step, students fill in missing calculations.
  6. Practice stations (15 min): Small groups rotate through three problem cards (free fall, horizontal projectile, inclined plane) applying the appropriate equation.
  7. Quick check (5 min): Exit ticket – one short problem to solve individually.
Conclusion:
Recap the three equations, emphasising when each is most useful and the importance of consistent sign conventions. Collect exit tickets to gauge understanding and assign a worksheet of additional problems for homework to reinforce the day's learning.
