Conservation of Momentum [IB Physics SL/HL]

This video explains the concept of conservation of momentum from Theme A of the IB Physics SL & HL courses. Firstly, Newton's laws are used to verify the fact that momentum is conserved in all isolated interactions between objects. The concept of elastic and inelastic collisions is then explained. Worked examples then follow: calculations are performed for elastic and inelastic collisions, and the situations of explosions and rockets are explored. Finally, a worked example of a two-dimensional collision is provided for the benefit of HL students. 0:00 Introduction 0:35 Proof of the law of conservation of momentum 1:51 Collisions 2:11 Elastic and inelastic collisions 3:14 Worked example 1: elastic collision 4:53 Worked example 2: inelastic collision 5:47 Explosions 6:14 Worked example 3: explosion 6:48 Rocket propulsion 7:46 Worked example 4: two-dimensional collision (HL only) 9:05 Summary More IB Physics Videos & Exam Questions can be found at: Revision Village - IB Physics https://www.revisionvillage.com
