What is the scientific method?
This is how fast an object travels.
What is speed?
This state of matter has no fixed volume or shape.
What is a gas?
This number tells us the number of protons and electrons a element has.
What is the atomic number?
This is a downward force.
What is gravity?
This is the average of a data set.
What is the mean?
This is the difference between initial and final position.
What is displacement?
This is stored energy.
What is potential energy?
We use this number with atomic number to determine the number of neutrons.
What is mass number?
What is the net force?
This is the factor in the experiment you are manipulating/changing.
What is the independent variable?
This is speed in a certain direction.
What is velocity?
The electrons that are used for bonding between elements. These electrons are either shared, lost or gained.
What are valence electrons?
The periodic table is split into metals, nonmetals and _________?
What are metalloids?
If the net force on an object is zero, the motion of the object does not change.
What is Newton's first law?
This is the factor you are measuring in an experiment.
What is the independent variable?
This is calculated from Speed multiplied by Time
What is distance?
The change of state from a solid to a gas without going through the liquid stage.
What is sublinination?
Outermost electron of an atom that participates in chemical bonding.
What is a valence electron?
The acceleration of an object is equal to the net force acting on the object divided by the object's mass.
What is Newton's Second Law?
These are the number of digits in a measurement that you know with a certain degree of reliability.
net force (N) / Mass (kg)
What is acceleration?
Uneven force acting on the particles on the surface of a liquid.
What is surface tension?
This is the name of the model used to show all the electrons of an element.
What is bohr atomic model?
This is the tendency of an object to resist a change in motion.
What is inertia?
