I remember enough physics to follow this, but not enough to reproduce it.

Gonna have to mull over this part some more:
“Just to be clear, ‘no changing’ [of Force] over time doesn’t mean that an object can’t experience a changing force along the course of its journey.
“The force might be different at different places, but at any particular place the force must remain the same.”
(“No change” means something different to me!)
Pretty colors!
