If a system interacts with objects outside itself, the total momentum of the system can change; however, any such change is balanced by changes in the momentum of objects outside the system. The most important thing to realize is that throughout a ball's trajectory, it will always be in any of these 4 different modes: sliding, rolling, spinning,stationary, or airborne (all of these states occur during the ball-cloth interaction, with the exception of the airborne state, which is covered later on ). Exam questions are based on topics and concepts covered in a typical high school physics course. In the real world, there are no purely elastic or inelastic collisions. Happy/Sad balls can come after demonstrating the large/small balls collision so the students have seen how energy can transfer and how it remains conserved. 2-dimensional momentum problem. Which one will go higher, or will they come back to the same height? Would love your thoughts, please comment. Hi I thought you multiply the net impulse force 3kg m/s by the time interval 0.02s but it is divided to give 150N, am I missing something? What are sports examples of transfer and conservation of momentum? At impact, the cue ball stops, but transfers all of its momentum to the other ball, resulting in the hit ball rolling with the initial speed of the cue ball. 9 - Browse the NGSS Engineering-aligned Physics Curriculum hub for additional Physics and Physical Science curriculum featuring Engineering.
