Re: [Phys-L] The Impulse Momentum Theorem

["Anthony Lapinski" <Anthony_Lapinski@pds.org>]

What does "better results" mean?

I prefer teaching momentum after energy so I can analyze energy
losses in collisions. This works very well.

Similarly, I teach circular motion/gravitation after forces,
and projectile motion after motion.

Not sure if there is a "preferred" topic order for mechanics.

I imagine some teachers start the year with forces.
We each have our own comfort level and teaching style.
