Angular momentum plays a key role in dealing with central forces because itis constant over time. Suppose the angular momentum, L, of a point mass isgiven by:By nature of the cross product, what two properties does L have?Show that: If a particle is subject to a central force only, then its angularmomentum is conserved i.e. If V(r) = V(r), then dL/dt = 0.

We have, L→=r→×p→ By the nature of cross product, the two properties that L→ has: L→ is a vector…

Angular momentum plays a key role in dealing with central forces because it is constant over time. Suppose the angular momentum, L, of a point mass is given by: 2=7 x p By nature of the cross product, what two properties does i have?
