Is it TRUE that angular momentum is conserved?
State the law that governs it
Answer
τ=ΔLΔt=L2−L1Δt0=L2−L1ΔtL2=L1\qquad\qquad \begin{aligned} \small \tau&=\small \frac{\Delta L}{\Delta t}\\ &=\small \frac{L_2-L_1}{\Delta t}\\ \small0&=\small \frac{L_2-L_1}{\Delta t}\\ \small L_2&=\small L_1 \end{aligned}τ0L2=ΔtΔL=ΔtL2−L1=ΔtL2−L1=L1
