Newton’s
Law
By: Brigitte Paulet
Sir Isaac Newton was born on January
4, 1643 - March 20, 1727. He mainly
worked on the absence of force,
weight, & speed. He also worked on
Philosophiae Naturalis Principia
Mathematica, which was published
on July 5, 1687. And the most
important one were his 3 Laws.
Newton’s First Law
There exists a set of inertial reference
frames relative to which all particles with
no net force acting on them will move
without change in their velocity. It’s
mostly simplified as “A body persists its
state of rest or of uniform motion unless
acted upon by external unbalanced
force.” It’s referred to as the law of
inertia.
Newton’s Second Law
The relationship between an object’s
mass m , its acceleration a, and the
applied force F is F = ma. It doesn’t apply
directly to situations where the mass is
changing. It’s applicable only If the force
is the net external force.
Newton’s Third Law
Newton’s Third Law is Motion. All forces
occur in equal but oppositely directed
pairs. There is a force of equal magnitude
but opposite direction that acts back on
the object which exerted that external
force. This Law is one of the fundamental
symmetry principles of the universe. It’s
useful for analyzing situations which are
somewhat counter-intuitive.
Galileo
Galileo was born in Pisa, Italy. He was
the first out of 6 children, of Vincenzo
Galilei. Which was a famous lutenist,
& music theorist. Well what both
Galileo & Isaac Newton worked on
was on forces.
