affected by gravity.
Essential Question(s)
What are the motions of objects in our solar system?
How does gravity cause these motions?

Gravity and Celestial Motion
Science
Formation of Our Solar System
Gravity is a "pulling" force that causes every particle of matter to
be attracted to every other particle of matter
Gravity formed our solar system from a nebula
Gravity formed our solar system from a nebula
 Nebulas consists of small particles of matter called cosmic dust
Notes

Gravity and Celestial Motion
Science
Gravity formed our solar system from a nebula
 Over time gravity pulled these particles together into clumps
Gravity causes our sun and planets to rotate (spin).
Gravity makes the planets revolve (orbit) around the sun

Gravity and Celestial Motion
Science
Gravity
causes our planet to rotate on its own axis
causes our planet to revolve (orbit) the sun
keeps our planet (and all the other planets) from “flying
off” into space as it revolves (orbits) around the sun
(Do demonstration of rotation vs. revolution)

Gravity and Celestial Motion
Science
Gravity keeps the moon from “flying off” as it orbits the Earth
(See Holt Online Ch15: Sect 4 Visual Concepts)
Notes
SPI 0807.12.6
Gravity and Celestial Motion
Science
1) What is one way gravity helped form our solar
system and planets?
A) By pulling matter together
B) By pushing matter apart
2) What is another way gravity helped form our solar
system and planets?
A) By making objects revolve and rotate
B) By making objects move in straight lines
3) Contrast revolution and rotation
A) Revolve=moving around another object,
Rotate=spinning on an axis
B) Revolving is faster than rotation and has more gravity
