Momentum and Impulse [IB Physics SL/HL]

This video explains the concepts of momentum and impulse from Theme A of the IB Physics SL & HL courses. The formula for momentum is introduced, and then Newton's second law is shown to be expressed in terms of net force and the rate of change of momentum. The relationship between momentum and impulse is then explained, and the use of force-time graphs to determine impulse is shown. A worked example demonstrates how to use the graph to determine the change in an object's momentum in a collision. 0:00 Introduction 0:18 Definition of linear momentum 1:35 Newton’s second law (momentum expression) 2:58 Impulse 4:02 Force-time graphs 4:41 Implications of impulse on collisions 5:33 Worked example: Force-time graph 7:01 Summary More IB Physics Videos & Exam Questions can be found at: Revision Village - IB Physics https://www.revisionvillage.com
