The ball bounce is the basis of the animation, including the energy attenuation of the bounce height, and the extrusion and tensile deformation during the bounce

Thank the teacher for helping me to criticize and revise my homework
I need to increase the height of the initial ball, increase the height attenuation,

At the same time, it is not appropriate to stretch too early in the process of squeezing and stretching in the air.

Also at the end, I need to keep the ball moving and add a bit of rolling to rest
