I do not know the Lagrangian or Hamiltonian principles of mechanics. However,I came to know that conservation of linear momentum,angular momentum and conservaton of energy lead to homogeneity of space,isotropy of space and homogeneity of time.Can anyone show why it is in purely Newtonian terms?I am familiar with virtual work methods...Otherwise if these conservation laws can be proved from the symmetry principles?You may also refer me to some link.(adsbygoogle = window.adsbygoogle || []).push({});
