Explain the energy changes that occur during oscillation in a simple harmonic motion system.
Model answer
What a good answer should say
- In a simple harmonic motion system, energy continuously transforms between kinetic energy and potential energy.
- At the maximum displacement, potential energy is at its maximum and kinetic energy is zero.
- As the object moves towards the equilibrium position, potential energy decreases while kinetic energy increases, reaching maximum kinetic energy at the equilibrium position.
Explanation
Why this works
This answer effectively demonstrates an understanding of energy transformations in simple harmonic motion, highlighting the relationship between kinetic and potential energy. It tests the student's ability to explain a fundamental concept in oscillatory motion.
