He came up with them by thinking deeply and obsessively. Sir
Isaac Newton was a genius, perhaps the greatest genius the world
has ever known. After inventing the eponymous fig-filled
pastry-like cookie -- the Fig Newton -- he yearned for more
difficult challenges and turned his attention to physics, writing
the *Philosophiæ Naturalis Principia Mathematica*, a
three-volume work published in July, 1687. It contains the
statement of Newton's laws of motion and his law of universal
gravitation.

### What were the names of Isaac Newton's three laws of motion?

Newton's First Law of Motion is referred to as the Law of
Inertia. It states that an object in motion will stay in motion
unless acted upon by an outside force.
The Second Law of Motion is the definition of Force : Force=mass
x acceleration.
The Third Law of Motion is the Law of Reciprocity. It states
that forces come in equal and opposite pairs. "Every action has an
equal and opposite reaction"

### What motivated Isaac Newton to do what he did?

Sir Isaac Newton is considered to be one of the most important
mathematicians to have ever existed. His theory of gravitational
force and his discovery of calculus are some of his most famous
achievements. There is a story that says that Isaac Newton was
sitting under an apple tree in England, and an apple fell and hit
him on his head. Apparently he jumped up and was so happy, because
he just realized gravity must exist, because the apple had a force
that did not come from anything. This story is said to have
motivated him to discover the gravitation force theory.

### What is the concept of force?

Definition: Force is a quantitative description of the
interaction between two physical bodies, such as an object and its
environment. Force is proportional to acceleration. In calculus
terms, force is the derivative of momentum with respect to time.
Contact force is defined as the force exerted when two
physical objects come in direct contact with each other. Other
forces, such as gravitation and electromagnetic forces, can exert
themselves even across the empty vacuum of space. The concept of
force was originally defined by Sir Isaac Newton in his three laws
of motion. Force is a vector. The SI unit for force is the
newton (N). One newton is equal to 1 kg * m/s2.
