| Lesson Topic: Define acceleration as change in velocity per unit time; recall and use the equation a = Δv / Δt |
Learning Objective/s:
- Describe acceleration as the change in velocity per unit time.
- Calculate acceleration using the formula a = Δv / Δt.
- Interpret the units of acceleration (m/s²).
- Solve basic acceleration problems involving given velocities and time intervals.
|
Materials Needed:
- Projector or interactive whiteboard
- IGCSE Physics textbook
- Worksheets with practice problems
- Stopwatch
- Toy car or video of an accelerating car
- Calculator
- Whiteboard and markers
|
Introduction:
Begin with a short video of a car speeding up to capture interest. Review the concept of velocity as a vector and ask students to recall how speed changes over time. Explain that today they will define acceleration and learn to calculate it using a = Δv / Δt, which will be the success criteria for the lesson.
|
Lesson Structure:
- Do‑Now (5'): Quick question on velocity differences posted on the board.
- Mini‑lecture (10'): Define acceleration, present the equation a = Δv / Δt, and discuss units.
- Guided example (10'): Work through the car problem step‑by‑step, calculating Δv, Δt, and a.
- Interactive activity (15'): Students use stopwatches and toy cars to measure acceleration and record data.
- Practice worksheet (10'): Individual problems while teacher circulates to address misconceptions.
- Check for understanding (5'): Exit ticket – one‑sentence definition of acceleration and a numeric calculation.
|
Conclusion:
Summarise that acceleration measures how quickly velocity changes and is expressed in m/s². Highlight how the equation a = Δv / Δt links the three quantities. For the exit ticket, students write a brief definition and calculate acceleration for a new scenario. Homework: complete the additional worksheet on acceleration problems.
