Final answer:
In physics, when two quantities are inversely proportional, one variable decreases as the other variable increases by the same factor. Examples include the time needed to travel to a destination and the speed of a car, as well as the acceleration of an object and its mass.
Step-by-step explanation:
In physics, when two quantities are inversely proportional to each other, it means that as one variable increases, the other variable decreases by the same factor. For example, the time needed to travel to a destination is inversely related to the speed of a car. If the speed of the car increases, the time needed to travel decreases, and vice versa.
This relationship can be seen in Newton's Second Law of Motion as well. The acceleration of an object is inversely proportional to its mass. The larger the mass of an object, the smaller the acceleration produced by a given force.
Another example of inverse proportionality in physics is Coulomb's law, where the electrical force between two charged objects decreases as the distance between them increases.
