Question

show that the angular momentum about any point of a single particle moving with constant velocity remains constant throughout the motion. ​

Answer 1

Answer:

Show that the angular momentum about any point of a single particle moving with constant velocity remains constant throughout the motion. ... As position of particle changes, r and θ both change, but rsinθ remains constant. Therefore, magnitude of →L=mvrsinθ=mv(OK)= constant. The direction of →L is ⊥→r and →v and inwards.
