The Law of Conservation of Energy is a fundamental concept in physics that states that energy cannot be created or destroyed in an isolated system; it can only be transformed from one form to another.

If there are no other forces on the system (Dimorphos plus DART), then these forces will lead to a conservation of momentum. We define momentum (p) as the product of an object's mass (m) and its ...
