Golf Ball hitting steel super slo mo
Why Physics Stack Exchange recommends it
Physics Stack Exchange answerers point people to it as a concrete visual of what actually happens during a collision, with the ball compressing, storing elastic energy and springing back.

What it is
A 37-second super slow motion clip of a golf ball striking a steel surface, showing the ball flatten against the steel and rebound. It is a simple demonstration posted by the channel BILLYKARLOFF with no narration or commentary.

Not an easy problem. See this video ( [this video] ) and realize there is a lot going on when a real bodies collide.

I think that what happens during the collision is perfectly illustrated by some frames of a golf ball hitting a rigidly fixed steel structure (wall). [LINK] Frame $1$ shows the ball with kinetic energy about to hit the wall. Frame $2$ shows some of the kinetic energy of the ball being converted into elastic potential energy in the ball (and the wall). Frame $3$ shows the ball at rest with the ball storing lots of elastic potential energy and having no kinetic energy. Frames $4$ and $5$ show the ball moving away with the elastic potential energy being converted back to the same amount of kinetic energy as the ball had before the collision. So during the collision kinetic energy was not conser

In general, Newtonian mechanics, that is taught at high school and at university in introductory level, considers objects as point particles or at most uncompressible solids. Therefore, in most cases, collisions are considered as elastic, where both kinetic energy and momentum are conserved. However, in reality this is far from being the case. There is almost no point particles and any solid can be compressed. In other words, in reality there is almost no elastic collision; some of the kinetic energy is spent for deforming the shape and eventually is lost as heat. There are a few materials properties (such as bulk modulus [LINK] ) involved in such calculations and I believe, analytical solut
