Explanation:

With the knowledge of the laws that govern the movement of bodies, we can predict where they are in the future and therefore know if there may be an accident, crash.

We can also know where they were in the past and therefore know if a fact is the result of these movements, craters, collapse of buildings, etc.

We can also build a device that generates a specific type of desired movement, for example pulleys that help us with work, etc.
