Question

The motion of a rocket is based on the principle of conservation of (A) linear momentum (B) mass (C) angular momentum (D) kinetic energy.

Tardigrade Admin · Accepted Answer

Taking rocket + fuel as system total linear momentum must be conserved since there is no external force. As the exhaust moves out with high speed towards the Earth , the rocket moves with same momentum away from the earth as the net momentum should be zero .
