Which of the following statements is true

1. In elastic collisions, the momentum is conserved but not in inelastic collisions
2. Both kinetic energy and momentum are conserved in elastic as well as inelastic collisions
3. Total kinetic energy is not conserved but momentum is conserved in inelastic collisions
4. Total kinetic energy is conserved in elastic collisions but momentum is not conserved in elastic collisions
