Momentum is conserved: In all cases, the ratio of final to initial momentum is close to 1, indicating that linear momentum is conserved during the collisions.This means that there is minimal energy loss during the collisions, and the objects rebound with minimal deformation.Elastic Collision Conditions:

Momentum is conserved: In all cases, the ratio of final to initial momentum is close to 1, indicating that linear momentum is conserved during the collisions.
Kinetic energy is not conserved: A significant amount of kinetic energy is lost during the collisions, as evident by the much lower final kinetic energy compared to the initial kinetic energy. This energy is often converted into other forms, such as heat, sound, or deformation of the objects involved.
Elastic Collision Conditions:

Momentum is conserved: The ratio of final to initial momentum is very close to 1, indicating that linear momentum is conserved during the collisions.
Kinetic energy is conserved: The ratio of final to initial kinetic energy is also very close to 1, suggesting that kinetic energy is conserved to a good approximation. This means that there is minimal energy loss during the collisions, and the objects rebound with minimal deformation.
