Explain how rocket propulsion is related to law of conservation of momentum.​

Answer 1

Explanation:

The outlying principle behind rocket propulsion happens to be the law of conservation of linear momentum. In other words, spacecrafts eject mass in a certain direction in order to be propelled in another.

Consider the following scenario: there’s a stationary spacecraft of finite mass [math]m_1[/math], and some amounts of fuel [math]m_2[/math] that gets ejected.

Before the mass ejects, you have the whole rocket to be stationary, which implies the net momentum is zero.

Answer 2

A rocket is an example of conservation of momentum where the mass of the system is not constant, since the rocket ejects fuel to provide thrust. The rocket equation gives us the change of velocity that the rocket obtains from burning a mass of fuel that decreases the total rocket mass.
