Hi Jonathan Have you derived the equations assuming that the system is static (i.e) the spring and mass based forces are in equilibrium and no external forces are involved?
@@gani3a9 can you please elaborate it ? it's still quite tricky to to me - I think there still need to have the gravitational force for sufficiency of illustration
Awesome and clear. Why has no one commented on this in years? Packed 2-3 lectures into one simple and concise 8 minute demonstration. Thank you.
my guy uno been struggling with this for time cheers son
Hi Jonathan

Brilliant, concise and clear. Thanks!
I thought that the arrow x1 always indicated positive direction. But that doesn't seem to be the case at 1:25
what about mg?
why the gravitation is zero?
Since force due to static deflection of spring cancels out weight of the body..
