## Main Question or Discussion Point

d

or

dA/dt=k=rv/2

How does dA/dt relate to

In a certain book, it says dA/dt=H/2 where H=

but

^{2}A/dt^{2}=0or

dA/dt=k=rv/2

**L**=**r**x**p****L**/m=**r**x**v****L**/(2m)=(**r**x**v**)/2How does dA/dt relate to

**L**?In a certain book, it says dA/dt=H/2 where H=

**L**/m=**rv**but

**L**is a vector and H is not.
