Subject: Physics
Lesson Topic: understand and use the terms displacement, amplitude, period, frequency, angular frequency and phase difference in the context of oscillations, and express the period in terms of both frequency and angular frequency
Learning Objective/s:
  • Describe displacement, amplitude, period, frequency, angular frequency, and phase difference in simple harmonic motion.
  • Derive and apply the relationships \(T = 1/f\) and \(\omega = 2\pi f\) to convert between period, frequency, and angular frequency.
  • Use SHM equations to solve problems involving mass‑spring systems and phase‑difference scenarios.
Materials Needed:
  • Projector or interactive whiteboard
  • Slide handout with key formulas
  • Mass‑spring apparatus (or digital simulation)
  • Worksheet of conversion and phase‑difference problems
  • Calculators
 Introduction:
Begin with a short video of a swinging pendulum to capture interest, then ask students to recall how they previously described waves. Highlight that today they will link those ideas to the precise language of oscillations. Success will be measured by their ability to state definitions and correctly convert between \(T\), \(f\), and \(\omega\).
Lesson Structure:
  1. Do‑now (5 min): quick quiz on wave terminology and previous formulas.
  2. Mini‑lecture (10 min): introduce SHM terms and the three core relationships using slides.
  3. Demonstration (8 min): mass‑spring setup; measure period and discuss observed amplitude.
  4. Guided practice (12 min): students complete worksheet converting between \(T\), \(f\), and \(\omega\) with teacher support.
  5. Collaborative activity (10 min): groups use a simulation to set a phase difference and predict the resulting curves.
  6. Check for understanding (5 min): exit ticket – write the period expressed in terms of angular frequency.
Conclusion:
Summarise the key definitions and the conversion formulas, confirming that students can move fluidly between period, frequency, and angular frequency. Collect exit tickets to gauge mastery, and assign a homework task to solve a real‑world mass‑spring problem using the derived equations.
