Project-Based Learning:
- Learners through PowerPoint presentations, flash cards and schematics define and explain angular displacement, angular velocity and angular acceleration.
- Let learners discuss the relationship between linear displacement and angular displacement, tangential velocity and angular velocity and tangential acceleration and angular acceleration. (Quantitative derivation of formula not needed).
- Let learners discuss and state the expression for centripetal acceleration and relate it to centripetal force. (Qualitative treatment only).
Encourage diverse perspectives and contributions.
