What is the purpose of units?
What is the purpose of units? For most quantities a unit is necessary to communicate values of that physical quantity. For example, conveying to someone a particular length without using some sort of unit is impossible, because a length cannot be described without a reference used to make sense of the value given. What are […]
What describes something in nature without attempting to explain it?
What describes something in nature without attempting to explain it? Unlike a theory, a scientific law describes an observed pattern in nature without attempting to explain it. A hypothesis is a possible explanation for a set of observations or answer to a scientific question. What do we call a description of how something works in […]
What are the two essential conditions for work done by a force acting on an object?
What are the two essential conditions for work done by a force acting on an object? For work to be done, it is essential that some force is applied to the object and the object displaces from its initial position. If these two conditions are satisfied, then the work is done. So, work done= force […]

Why does O 3 not exist?
Why does O 3 not exist? An electrically-neutral oxygen atom gains two electrons to form an oxygen ion with two negative charges. The ion would thus be highly unstable and potentially readily lose that outermost electron and return to O3− as the ten inner shell electrons seek to get rid of the additional electron. Why […]
