Intro:
Resist the twist
Resist the twist 

Verse 1:
The ice skater gracefully glides
Then pulls her arms in towards her sides
Reducing her moment of inertia's span
As her spin rate increases on demand

Chorus:
Angular momentum of a system remains constant, constant, 
unless a net torque is acting
it remains constant, constant

Verse 2:
Moment of inertia, rotational bane
An object's resistance to angular change
The way that mass is dispersed all around
Governs how easily it can spin round

Chorus:
Angular momentum of a system remains constant, constant, 
unless a net torque is acting.
it remains constant, constant

Verse 3: 
Angular impulse, the momentum's change
Torque-time area gives that impulse main
The area inscribed by torque and time
Reveals the angular impulse, sublime

Chorus:
Angular momentum of a system remains constant, constant, 
unless a net torque is acting.
it remains constant, constant
