What is gravity?
The force that holds us to the earth.
Two
What is the difference between a linear and non-linear graph?
A linear graph has data points that are positioned in a straight line.
Kinetic Energy is:
Energy that is in motion.
How does the mass of an object affect the amount of gravity on that object?
The more mass the object has, the greater the gravitational pull.
What two variables do you need to know in order measure speed?
A.) Time and direction
B.) Time and distance
C.) Force and distance
B.) Time and distance
What does the unit (N) stand for?
Newtons
Define Newton's Third Law.
For every action there is an equal and opposite reaction.
What was the force responsible for causing the levitating orb to float?
Static Electricity
If force increases as a result of mass increasing, is this a negative or positive correlation?
Positive Correlation
In an experiment, we manipulated the amount of mass in a grocery bag and measured how the force of gravity changed. What variable, mass or force, belongs on the x-axis of our graph?
Mass
How was the fire-extinguisher go-kart related to Newton's Third Law?
The direction of force and the direction of movement were both equal and opposite.
What is the opposing force of gravity when an object is falling?
Air resistence
What is the difference between speed and velocity?
What button do we push on a scale to "zero" it out so that the numbers read BEFORE you place the item on it says 0.00?
The tare button or "T".
How were the rocket sled, fire extinguisher go-kart and hovercraft all related?
You must use one vocabulary word in your answer.
Answers may vary.
They all had kinetic energy.
They all were examples of Newton's Third Law.
What happens to your mass when you go on the moon?
It stays the same.
