Oscillations
What students will learn
Explain restoring-force motion, connect its graphs and energy, and use measurements to test an oscillator model.
Before this topic
- Newton’s laws
- Spring-force graphs
- Energy conservation and graph slopes
Read and connect
Supporting reading: Spring Forces →
Review relaxed length, equilibrium, and the difference between spring force and restoring net force.
Before this connection: Force diagrams.
Supporting reading: Conservation of Energy →
Review the chosen system and energy account before modeling spring motion.
Before this connection: Potential energy.
Read: Simple Harmonic Motion: The Force That Brings You Back →
Identify equilibrium and test the restoring-force condition for simple harmonic motion.
Read: Period and Frequency: What Sets the Pace? →
Compare periods and frequencies and plan measurements for spring and small-angle pendulum models.
Read: Reading SHM: Position, Velocity, and Acceleration →
Connect position, velocity, and acceleration graphs with slopes, signs, and turning points.
Read: Oscillator Energy: Where Did the Speed Go? →
Track oscillator kinetic and potential energy, including the vertical spring-gravity system.
Read: Experiment, Explain, and Show Your Work →
Use the reusable reasoning toolkit to design a pendulum investigation and connect data, representations, and justified conclusions.
Check understanding
Use the complete prompt to make student reasoning visible, then consult the separate worked reasoning and criteria. A reading completion tick records reading history.
Turn measured oscillator positions into graphs →
Plot numerical data, estimate amplitude and period, relate velocity and acceleration, and compare the model with measurement uncertainty.
A short record can support consistency with SHM without proving unique or future behavior.
Design a pendulum investigation →
Specify measurements, controls, repeats, and a linearized graph; estimate g from supplied data and discuss a systematic error.
The task asks for an investigation plan and supplied-data analysis; completing it does not verify hands-on laboratory participation.
