τ_net= Iα	τ = r F sinθ	τ = r F
Linear to Rotational Conversions
x = rθ	v=rω	a=rα
Rotational Kinematics
∆θ = ωit + ½αt²	ω = ωi + αt	ω² = ωi² + 2α∆θ
Rotational Momentum
L = Iω	K = ½Iω²	∆L= τ∆t

When Momentum is Conversed:	∑pi = ∑pf
p = mv	∆p = F∆t or J = F∆t	pf = pi + J
Types of Collisions
Elastic Collision	KE conserved & momentum conserved	Bounce perfectly off each other
Inelastic Collision	KE lost & momentum conserved	Travel in same direction at different speeds
Perfectly Inelastic Collision	Greatest KE lost & momentum conserved	Objects coupled and travel in same direction
