Homework Statement
At time t, particle with mass m has displacement ##\vec r (t)## relative to origin O. Write a formula for its angular momentum about O and discuss whether this depends on choice of origin.
The second part is what I'm more unsure of.
Homework Equations
The Attempt at a Solution
##\vec l=\vec r\times\vec p## so at time t, ##\vec l=\vec r(t)\times m\vec v##
For the second part, I wasn't sure what to do. I tried and got as far as this:
##\vec l_2=\vec r_2\times m\vec v_2##
Then ##\vec l-\vec l_2=(\vec r\times m\vec v)-(\vec r_2\times m\vec v_2)##
What now?
