New cards
Angular momentum
L = r x p = rmvsinΦ
Cross-product: 3 way (i, j, k), results in k vector
2
New cards
Ang. momentum & velocity
L = Iω
3
New cards
Torque (vector)
τ = r x F
4
New cards
Gyroscopic precession
When already-spinning objects rotate in unexpected ways, where their momentum vector “follows” the force/torque vector
5
New cards
Precessional frequency
ωr = MgrCM/Iω
