Practicing Success
Which of the following principle governs the working of a rocket? |
Principle of conservation of angular momentum Principle of conservation of linear momentum Principle of conservation of mechanical energy All of these |
Principle of conservation of linear momentum |
Principle of conservation of linear momentum: If no external force acts on a system of bodies, the total linear momentum of the system of bodies remains constant. As a consequence, the total momentum of bodies before and after collision remains the same. Rocket works on the principle of conservation of linear momentum. |
