This series of posts aims to provide a comprehensive understanding of momentum in physics. Starting with an introduction to momentum, we will explore its equation, units, and its significance in the field. We will then delve into the relationship between impulse and change in momentum, discussing the concept of impulse and how it affects an object's momentum. Next, we will examine the principle of conservation of momentum, which states that the total momentum of a closed system remains constant during collisions or explosions. Additionally, we will explore the differences between elastic and inelastic collisions, including the conservation of kinetic energy and the coefficient of restitution. Lastly, we will explore practical applications of momentum in various real-life scenarios, such as sports, car safety, and rocket propulsion systems.
