... In an experiment to verify the principle of conservation of momentum for a collision between two bodies, A and B, the following was recorded. Mass of A is o.2 Kg Mass of B is 0.4 Kg Before the collision, body A moves 0.45 m in 0.3 s. Before the collision, body B is at rest. After the collision, bodi ...

Transformations and conservation laws

Thus there is an infinite number of inertial frames. The equations of motion are invariant with respect t ...
