Скачать или смотреть NCEA Physics | Quadratic Equations in Motion Problems | Algebra for Time | Year 11–12 NZ

This video is an NCEA Physics lesson for New Zealand students focusing on how quadratic equations are used to solve motion problems, particularly when calculating time.

In this session, we review physics questions involving constant acceleration and then develop the algebra needed to solve them, including factorisation and the quadratic formula.

Topics covered in this lesson include:
✔ Using v = u + at to solve velocity problems
✔ Identifying given values and what is being asked in physics questions
✔ Rearranging motion equations into quadratic form
✔ Understanding quadratic equations (ax² + bx + c = 0)
✔ Solving quadratics by factorisation
✔ Solving quadratics using the quadratic formula
✔ Verifying solutions by substitution
✔ Interpreting negative solutions in physics contexts
✔ Deciding which solution is physically meaningful (e.g. time cannot be negative)

This lesson helps students:
• Connect algebra skills with real NCEA Physics questions
• Understand why quadratic equations appear in motion problems
• Choose the correct mathematical method for each question
• Build confidence with multi-step physics calculations

This video is suitable for:
• Year 11 NCEA Physics students
• Year 12 NCEA Physics students
• Students revising quadratic equations for Physics
• Learners preparing for NCEA internals and externals
