User Suggestion: Displacement arrow from mass equilibrium #369

Open PaulTorry opened 3 years ago

PaulTorry commented 3 years ago

To make the connection to the defining equation of SHM a=-w^2x it would be helpful to have an arrow showing displacement from equilibrium.

One option would be to have the displacement option separate to natural length and if either Natural Length or Mass equilibrium is ticked it shows the relevant arrow (or both?)

PaulTorry commented 3 years ago

To clarify I believe... the current arrow showing displacement would be better termed extension (from natural length) the term displacement should instead mean displacement from equilibrium

I am not sure if this is a localisation difference. For reference I am British, the term may be different in the US or elsewhere

Sorry, still getting used to github.
