Scientific Method
Can the Scientific Method only be used for scientific research?
No, it can be used for many situations.
What is Tension Force?
Force that is stretched across an object like a rope/string
What is the equation to calculate speed? (Speed = …)
Speed = Distance / Time
What does Newton’s 1st Law of Motion state?
An object at rest stays at rest, and an object in motion stays in motion, unless acted upon by an outside force.
What is the major source of energy that almost all energy used on Earth comes from?
The Sun
What are the charges of Protons, Neutrons, and Electrons?
Protons = Positive
Neutrons = Neutral
Electrons = Negative
What happens to the amount of Electron Shells elements have as you go down the Periodic Table?
The number of shells increases
What type of energy/reaction fuels stars?
Nuclear Energy (Fusion Reactions)
What step of the Scientific Method requires you to make an educated guess about what you think will happen?
Hypothesis
What is Gravity?
A force that all objects have that pulls them together. On Earth this pulls objects downward
What does it look like when something is moving relative to something else?
An object is moving from the perspective of another object. (ex: A person on the sidewalk watching a car pass by.)
What does Newton’s 2nd Law of Motion State, when reduced down to a simple equation?
Force = mass x acceleration
What is the Law of Conservation of Energy?
Energy cannot be created or destroyed, only transferred from one type to another.
What are Ions?
Charged versions of Elements
How many electrons does it take to completely fill the 1st Electron Shell (the inner-most shell) of an atom?
2 Electrons
What types of stars become Black Holes?
Large Mass stars (the biggest stars in the universe)
What step of the scientific method do you take after you collect your data and look for patterns in the data?
Analyze the Data
What is Applied Force?
A person or object directly pushing/pulling another object (ex: someone pushing a cup off their desk)
If two objects are both moving at the same speed and the same direction, are they moving relative to each other?
No, from their perspective they are both not moving. (ex: two people sitting on a bus)
What does Newton’s 3rd Law of Motion State?
Every action has an equal and opposite reaction.
What is Sound Energy?
Energy that is transferred through vibrations, usually moving through the air around us
What two states can isotopes be in?
Stable or Radioactive
How many electrons does it take to completely fill the 2nd and 3rd Electron Shells of an atom?
8 Electrons
Where do most of the elements of The Periodic Table come from? (forgot to put this one on your review packet)
From the immense fusion from a star going Supernova (a star explosion).
What is qualitative data vs what is quantitative data.
Qualitative Data=Data that describes qualities (ex: color, texture, etc)
Quantitative Data=Data measured with numbers (ex:10 in, 400 pounds, etc)
What is Friction?
The force working against applied force that resists motion of two surfaces rubbing against each other
What is the difference between Speed and Velocity?
Speed = How fast something is going
Velocity = How fast something is going and in what direction
What law of motion is responsible for recoil? (an equal and opposite reaction)
Newton's 3rd Law
What is Kinetic Energy Associated with?/What is Potential Energy Associated with?
Kinetic Energy = movement
Potential Energy = stored energy
What is the name of the rule that states: Elements are most stable when they have a completely full Valence Shell.
The Octet Rule
What type of celestial body is currently thought to be the largest single object in the Universe?
A black hole
What is the Peer Review Process?
The process following the Scientific Method where your findings are verified by others
What two types of information does a vector display? (Hint: remember Despicable Me)
Vector = Both direction and magnitude
What is the link between Chemical Bonds and Chemical Reactions?
Chemical reactions are when chemical bonds are either being broken, formed, or both.
What happened during the Apollo 13 Mission?
The NASA mission that was meant to be the 3rd manned lunar landing, but instead resulted in an explosion in space and turned into a rescue mission to get all three members of the crew back to Earth safely?
