Object physics makes the game more realistic in terms of objects interacting with gravity. Before, when you put down an item, it would start to float on the ground. Now the project will lay flat on the ground-as it should be. The new physics only applies to the items shown in the figure below. For items that fall into lava, Netherite items will have a funny little animation.
