What is inertia?
Inertia is the tendency of objects in motion to stay in motion and objects at rest to stay at rest, unless a force causes the velocity to change.
100
What does waning mean?
Waning means decreasing, and is used to describe the moon's phases when it appears to get smaller each night.

Without using paper is 2Al + 3F2→ 2AlF3 balanced or not?
Balanced
100
What moon is this?
Waning gibbous
200
What does unbalanced mean?
An object causes a change in the motion of the object. The objects can change direction, speed up, or slow down.
200
How many moon phases do we see?
8 phases
200
What are molecules?
A group of atoms bonded together
200
Using paper, is C₃H₈ + 5 O₂ → 4 H₂O + 3CO₂ balanced?
Yes
200
What is third quarter also known as?
The last quarter moon
300
What does Newton's first law of motion say?
Newton's first law of motion says that an object's motion remains the same unless a force acts on the object.
300
What phase does the moon show in a lunar eclipse?
Full moon
300
What are compounds?
A substance made up of two or more elements that are chemically bonded together
300
Using paper, is C₂H₆O + 3 O₂ → 3 H₂O + 3 CO₂ balanced?
Yes
300
What comes after a waning crescent?
A new moon
400
When you push the door it pushes back and equals an opposite force. What law of motion is this?
Newton's third law of motion
400
What is the order of celestial bodies during a solar eclipse?
Sun, Moon, Earth
400
What are elements?
A pure substance that can't be broken down into other substances.
400
Without using paper, is CH₄ + 2 O₂ → CO₂ + 2 H₂O
NO
400
This moon is half lit and appears to be getting bright
first quarter
500
What is the 2nd law of motion?
The force acting on an object is equal to the mass of the object multiplied by its acceleration. (F= ma)
500
What is the order of celestial bodies during a lunar eclipse?
Sun, Earth, Moon
500
What is the difference between a chemical and physical changes?
A chemical change forms new substances.
A physical change affects the state, or form of a substance, but not its chemical composition.
500
Without using paper, is CH₄ + O₂ → CO₂ + H₂O balanced?
NO
