Lesson Plan

• Define displacement, velocity, and acceleration for straight‑line motion.
• Distinguish between average and instantaneous quantities.
• Apply the three equations of motion to solve constant‑acceleration problems.
• Construct and interpret displacement‑time, velocity‑time, and acceleration‑time graphs.

• Projector and screen
• Whiteboard and markers
• Printed worksheets with practice questions
• Graph paper, ruler, and calculators
• PhET “Moving Man” simulation (or similar)
• Set of small toy cars for a quick demonstration

Begin with a short video of a car accelerating down a straight road to capture interest. Review students’ prior knowledge of vectors and basic algebraic manipulation. Explain that by the end of the lesson they will be able to solve kinematics problems and accurately sketch the related graphs.

1. Do‑now (5'): Quick quiz on displacement vs. distance and average vs. instantaneous speed.
2. Mini‑lecture (10'): Definitions of displacement, velocity, acceleration; introduce the three equations of motion.
3. Guided example (10'): Work through the car‑acceleration problem step‑by‑step, highlighting algebraic substitutions.
4. Graph activity (10'): Students plot displacement‑time, velocity‑time, and acceleration‑time graphs using the example data.
5. Collaborative practice (15'): Small groups solve the three practice questions from the source material, checking answers with peers.
6. Check for understanding (5'): Exit ticket – one short problem requiring selection of the correct equation and a brief sketch.

Summarise the link between the algebraic equations and their graphical representations, emphasizing correct sign usage. Collect exit tickets to gauge mastery, and assign a worksheet with two additional constant‑acceleration problems for homework.
