Conservation of Linear Momentum - AP Physics

Learn the fundamental principle of conservation of linear momentum in this 15-minute physics video lesson. Explore how linear momentum remains conserved in all interactions when the net external force on a system is zero, and understand how momentum transfers between systems and their environment when external forces are present. Begin with understanding momentum of a single particle before diving into the conservation principle itself. Work through practical calculations to determine object velocities immediately before or after collisions and explosions. Perform sense checks to verify your solutions and examine real-world applications of momentum conservation. Connect these concepts to Newton's third law and discover the historical contributions of Emmy Noether to conservation principles in physics. Master essential problem-solving techniques for AP Physics while building a solid foundation in one of physics' most important conservation laws.
