After the game opens, head into the settings and look for Physics Settings.

The mod adds more realistic physics to the game, something that is not present by default. This includes a variety of types of physics, such as mob ragdoll physics and fracturing, particle blocks, and more. As mentioned, this mod is built for Minecraft, so the user will need to own Minecraft if they want to use the mod.

Now open the official launcher of Minecraft. Select the game version: Fabric 1.21.5 When the game opens, go to settings and there you should see a Physics Settings option. If it is visible, it means the mod has been installed correctly. If you are using any mob animation resource pack, disable it. Otherwise the ragdoll effect will not look right.
