Imagine that two balls of the same mass move towards each other with the same velocity (in opposite directions) and then collide absolutely inelastic so at the end we have one entire body at rest. So momentum is conserved (and equal to zero). the greenock cut walk map

"WebMomentum can be conserved in these types of collisions; kinetic energy is not conserved. Results from data table 7 show that while momentum was conserved, as on average 87% of the initial kinetic energy for collisions 4.1 and 4.2 was lost. With collisions 5.1 and 5.2, on average 67% of the initial kinetic energy was lost. " - Can momentum not be conserved

What happens if energy is not conserved ...

WebThe conservation of momentum principle can be applied to systems as different as a comet striking Earth and a gas containing huge numbers of atoms and molecules. Conservation of momentum is violated only when the net external force is not zero. But another larger system can always be considered in which momentum is conserved by … WebAug 9, 2024 · In this case angular momentum is conserved about the first point whereas it is not about the second. As an example, consider a particle in free fall. The torque due to gravity about any point in the vertical line containing the particle vanishes and therefore the angular momentum about that point is conserved. For the same system, consider a ...
