Choose the correct statement.
1
The angular momentum is conserved for systems possessing rotational symmetry.
2
If the Lagrangian of a system is invariant under translation along a direction, the corresponding linear momentum is not conserved.
3
If the Lagrangian of a system is not invariant under translation along a direction, one cannot say anything about the corresponding linear momentum.
4
For a conservative system, the Hamiltonian is not equal to the sum of kinetic and potential energies.
