Newton's First Law of Motion: History, Explanation, and Real-Life Examples Introduction to Newton's First Law of Motion Newton's First Law of Motion represents one of the principal cornerstones of classical physics and thus is an inevitable part of the discussion about mechanics. It is this law that tells us how the objects will behave when some forces are applied to them or when there is no force at all. The law is, indeed, that of inertia, and it is the one that describes the innate tendency of an object to resist motion change. It does not matter whether the object is not moving or it is moving very fast, in either case it will not change its state unless a force that comes from outside acts upon it. This idea, simple but very powerful, is a basis for understanding such a common experience as why a book lying on a table does not fall down or why a car running along the road does not come to a sudden stop without applying brakes. Historical Background of Newton’s First La...

What Is Focus and Why It Matters Focus can be defined as the capacity to give one’s full attention to a single task or activity without allowing oneself to be distracted by anything else. The brain's prefrontal cortex is responsible for the functions of attention and decision-making. It has been found in research that this part of the brain can only perform one or two tasks really well at a time. Scientific Example: The American Psychological Association states that productivity when multitasking can be reduced by as much as 40%. When focus is improved, it me...
