Explanation Calculation: Consider v i is velocity of particle with respect to a frame OXYZ . Consider r i is position vector of particle with respect to a frame OXYZ . Consider r ′ i is position vector of particle with respect to a frame A x ′ y ′ z ′ . Consider v ′ i is velocity of particle with respect to a frame A x ′ y ′ z ′ . Express the velocity of particle with respect to a frame OXYZ . v i = v A + v ′ i Express the angular momentum using the relation as follows: H A = ∑ i = 1 n r ′ i × m i v i (1) Substitute v A + v ′ i for v i in Equation (1). H A = ∑ i = 1 n r ′ i × m i ( v A + v ′ i ) = ∑ i = 1 n r ′ i × m i v A + ∑ i = 1 n r ′ i × m i
