Newton's laws of motion

Newton's laws of motion as a Venn diagram

Newton's laws of motion are three fundamental laws describing the dynamic behavior of objects (see dynamics),
first published by Isaac Newton in his great work Principia in 1687. They are as follows:
1st law
A body will remain in a state of rest or uniform motion unless acted upon
by a net external force. The first law is
also called the "law of inertia" because it enshrines the concept
of inertia as developed by Galileo.
2nd law
The net force on a body is equal to the product of the body's mass and its acceleration (i.e., the rate
of change of momentum). Acceleration and
force are vectors. In the second law, the
directions of the force vector and the acceleration vector are the same.
3rd law
When two bodies interact, the force on the first due to the second is equal
and opposite to the force on the second due to the first. In other words,
action and reaction are equal and opposite. (See also D'Alembert's
principle).
