SHS3 Physics · Semester 1 Week 9: Kinematics

Lesson notes

Learning Objectives

Indicator: 3.1.2.LI.1 - Explain simple harmonic motion and give some examples of such type of motion.

By the end of the lesson, learners can:

Define simple harmonic motion (SHM) in their own words using the key conditions of acceleration proportional to displacement and directed towards equilibrium.
Identify at least five examples of SHM from everyday life, including pendulums, springs, and vibrating strings.
Distinguish between SHM and other periodic motions such as circular motion and simple vibration.
Set up and observe an oscillating spring-mass system to verify the characteristics of SHM.
Explain the role of restoring force in producing simple harmonic motion.

Exemplars (from the NaCCA curriculum)

Collaborative and experiential learning: Using videos or laboratory set up of oscillatory motions, learners come out with the definition of SHM and examples of SHM.
Foster an inclusive and respectful classroom culture and address bias in teaching materials and examples.
Assessment (3.1.2.AS.1). The document marks these depth-of-knowledge levels for this indicator: Level 1 Recall.
