Question

show that angular momentum is constant using equation 0=m(2r°theta°+r theta°°)​

Answer 1

Answer:

This equation is an analog to the definition of linear momentum as p = mv. Units for linear momentum are kg ⋅ m/s while units for angular momentum are kg ⋅ m2/s. As we would expect, an object that has a large moment of inertia I, such as Earth, has a very large angular momentum. An object that has a large angular velocity ω, such as a centrifuge, also has a rather large angular momentum.
