This series introduces the fundamental concept of conservation of momentum and its significance in physics. It explores the relationship between Newton's third law of motion and the conservation of momentum, discussing how action and reaction forces impact the momentum of objects involved in collisions. The series covers both elastic and inelastic collisions, explaining how momentum is conserved in each case. Real-life examples are provided throughout to enhance students' understanding of the concept. The applications of conservation of momentum in various contexts are also explored, highlighting its importance in everyday life.
