C.1.2—SHM defining equation Topic Practice
Use the defining SHM equation to read signs, compare positions and extract angular frequency from acceleration-displacement data.
How this is tested
- use the gradient of an acceleration-displacement graph to obtain -omega^2, then find f
- apply a = -omega^2x to compare acceleration magnitude and sign at labelled displacements
- use x-t or a-t graphs to identify that displacement and acceleration are pi out of phase
