Famous scientific laws

As long as we're talking about one of the greatest scientists who ever lived, let's move on to Newton's other famous laws. His three laws of motion form an essential component of modern physics. And like many scientific laws, they're rather elegant in their simplicity.

The first of the three laws states an object in motion stays in motion unless acted upon by an outside force. For a ball rolling across the floor, that outside force could be the friction between the ball and the floor, or it could be the toddler that kicks the ball in another direction.

The second law establishes a connection between an object's mass () and its acceleration (a), in the form of the equation F = m a. represents force, measured in Newtons. It's also a vector, meaning it has a directional component. Owing to its acceleration, that ball rolling across the floor has a particular vector, a direction in which it's traveling, and it's accounted for in calculating its force.

The third law is rather pithy and should be familiar to you: For every action there is an equal and opposite reaction. That is, for every force applied to an object or surface, that object pushes back with equal force.

What are the three scientific laws.

Every second of every day, you and I are working to frustrate this Law, to perhaps break this Law, albeit for a momentary blip in time.  Humans are the manifestation of nature's ultimate rebel, flexing and contorting this law to it's whim, flaunting it's successes and teasing it to be gone.  This Law cares not who we are, what we are doing and why we are doing it.  This Law is the beginning and end of just about all Laws, both natural laws and human created Laws.
