Physics · Classical Mechanics
Two non-relativistic particles with masses m1 and m2 move with momenta p1 and p2, respectively, in an inertial frame S. In another inertial frame S', moving with a constant velocity relative to S, the same particles are observed to have momenta p'1 and p'2. Galilean invariance implies that:

- 1m1p'1 + m2p'2 = m1p1 + m2p2
- 2m1p'1 - m2p'2 = m1p1 - m2p2
- 3m2p'1 + m1p'2 = m2p1 + m1p2
- 4m2p'1 - m1p'2 = m2p1 - m1p2✓
Correct answer
m2p'1 - m1p'2 = m2p1 - m1p2
