Physics Lab- Momentum and Impulse- Egg Baseball
This video is very similiar to the experiment we performed in class. It provides a slow motion view as well as a clear explanation and step by step process of the experiment. The video justifies that because P=MV and therefore both eggs go from moving to not moving when the eggs impact their different barriers, the change in momentum is the same whether it hits the plate, blanket, or fence. Furthermore if change in P is the same, then so is J or the impulse as J=P. However, since the impulse formual is J=FT, If the time increases the force therefore must decrease to retain J=P.
