The rocket equation is a unique case where the law of conservation of linear momentum needs to be used with some caution. Unlike most cases, here the mass of each of the body under consideration (rocket and fuel) changes every moment.
Watch this video to learn how the velocity of a rocket is related to the rate of change of mass of the rocket

ABOUT “THE SCIENCE CUBE”
Physics for class 11 and 12 is a significant step-up from class 10. Rushing into understanding topics like circular motion, electricity, “moment of inertia” etc. can leave a student disinterested in the subject over a period of time.
“The Science Cube” has come about from my experience of teaching over the years and how intricate topics like “integral calculus”, vectors, Newton’s laws of motion etc. are absorbed by young students.
I really hope that this channel can make the students appreciate the subject and help them ace their exams.
Who can use:
Class 11 and 12 students (CBSE, ICSE, NCERT)
IIT-JEE Preparation (JEE Main and JEE advanced)
K-12
Advanced Placement (AP Physics)
Subject SAT
