Any two bodies in the universe attract each other with a force

that is directly proportional

and

inversely
proportional to the square
of the distance between

them.

Telescope

Newtonian telescope is a type of reflecting
telescope invented by Newton, using a concave
오목주경
primary mirror, and a flat diagonal secondary
mirror. This is the earliest known functional
reflecting telescope. Even now, the Newtonian
telescope's simple design makes it very popular
with amateur telescope makers.
Newton’s
laws of motion
First law: When viewed in an inertial
좌표계 frame, an object either remains
reference
at rest or continues to move at a constant
velocity, unless acted upon by an external
force. 관성의 법칙
Second law: The vector sum of the
forces F on an object is equal to the
mass m of that object multiplied by
the acceleration vector a of the object:
F = ma. 힘과 가속도의 법칙
Third law: When one body exerts a force
on a second body, the second body
simultaneously exerts a force equal in
magnitude and opposite in direction on
the first body. 작용과 반작용의 법칙
