Stud welding uses a type of flux called a ferrule, a ceramic ring which concentrates the heat generated, prevents oxidation and retains the molten metal in the weld zone. The ferrule is broken off of the fastener after the weld is completed.
Inertia is a nice and easy physics lessons for kids and children. In physics, inertia is part of Isaac Newtonâs First Law of Motion simply stating that a particular object at rest will stay in that state unless otherwise a force is put on it for the object to move.
The faster the car is moving â the greater force is also required to stop it. For kids, an easy example to demonstrate inertia would be objects that they can relate to, like a starfish. Though starfishes can crawl pretty slowly at the bottom of the ocean floor, most kids see them as just ânon-movingâ animals.
