Theme or Central Idea: Attractive gravitational forces exists between all objects that have a mass.
Supporting Detail:
A. What was Newton’s idea
about gravity?
B. What does the law mean?
Supporting Detail:
A. What is “G”?
B. What is the reaction
partner of gravitation?
Supporting Detail:
A. What direction is the force
of gravity?
B. Gravity?
C. What is a satellite?
Supporting Detail:
A. Orbits and planets.
B. What orbits what?
Supporting Detail:
A. Gravitational force
happens between objects
that have a mass.
A. A constant in the
universe.
6.67 X 10-11
Its unit is: N m2/kg2
A. Always a line between two
objects.
A. Orbits are circular which is
a type of ellipse.
a. Planets orbit a star
(Sun)
b. Satellites orbit
planets.
c. Comets follow
elliptical orbits
around a star.
Move faster as
they approach
star.
B. Smaller mass orbits a larger
mass.
A. No. The path depends on the
ratio of its tangential velocity
to its radial velocity.
Tangential is 90o of radial
velocity. The resultant
direction is its path or
trajectory.
B.
B.
m1
m2
Radius
Forces are proportional due to
mass and inversely
proportional to the square of
the radius of the centers.
Must come in pairs
a. Action force is
acting on m1
from m2.
b. Reaction force is
acting on m2
from m1.
B.
It takes a planet-sized
mass to make a force
strong enough to feel,
gravity.
a. Mass of Earth
5.98 X1024 kg
C.
Natural or human-made
object that attracted to a
larger object.
The path it takes around
larger object is orbit.
Examples:
a. our moon
b. Hubble
c. Space station
A. Does gravity bend all paths
into orbits?
Write a story which applies what you just read from these sections. Focus on using key terms and information from each section above in your story.
Once upon a time the Mike Moon had a big brother Ed Earth that he ran around with because Ed was bigger. (Orbit). Mike’s big brother then ran around his big dad
SamSUN (orbit). The closer they came to each other their bonds became stronger. Their dog Comet ran around SamSUN. Comet would speed up every time he came closer
to SamSUN.
