Question

prove Law of Conservation of Linear Momentum by using Newton's third law​

Answer 1

Answer:

proof

Explanation:

consider two bodies of mass A and Mass B

then change in momentum = m A (va-ua)/t

and

mb (vb-ub)/t

Fab = -Fba (here - indicates opposite direction )

ma (va-ua)/t= -mb (vb-ub)/t

this gives

maua + mbub = mava + mbub
