Physics formulas are based on how objects move. By calculating the forces on an object, scientists can predict where the object will go, how far it will go, and when it will arrive. Scientists can then make accurate predictions without manipulating the object at all. This is especially useful for objects that are physically impossible to experiment with. Physics is the backbone to from
