SUMMARY

The optimal placement of a fiducial marker in simple harmonic motion (SHM) systems, specifically in a mass on a spring system and a simple pendulum, is crucial for accurate motion tracking. For a simple pendulum, the marker should be positioned below the bob at the equilibrium position, where the bob achieves maximum speed and minimal transit time. Placing the marker below the suspension point would result in negligible movement, thus reducing tracking effectiveness. This strategic positioning enhances the fidelity of motion capture in SHM systems.

Homework Statement


Where would be the perfect place to place a fiducial marker in a: mass on a spring system (vertical) and a simple pendulum?

Homework Equations

The Attempt at a Solution



My teacher told me that for a simple pendulum it would be below the bob at equillibrium position because this is the point where the bob has its max. speed or the transit time is the smallest

But I have no idea why this would mean that the below the bob would be better then anywhere else

Wouldn't it interfere if it was placed anywhere else?
 
If you put the mark right below the suspension point, there would be virtually no movement at all. If you want to maximise the movement, you need to be near (even beyond) the bob.
