About This Product
A mass on a spring is one of the easiest oscillators to explain, because students can link Hooke’s Law directly to simple harmonic motion. They pull the platform down, release it, measure the frequency and compare it with theory, then use the waveforms to confirm the phase difference between displacement and acceleration.
Frequently Asked Questions
What does the software show?
Displacement and acceleration waveforms, so students can see the phase difference and measure frequency. It also calculates velocity and acceleration from the displacement, so measured and derived acceleration can be compared.
