Dependent Variable - ANS-A variable that changes in response
to the changing independent variable
Interpolation - ANS-Estimating a value within a set of data points
on a graph
Scientific Method - ANS-A methodical way to test a Hypothesis,
based on data collection having controlled variables
Displacement - ANS-An object's overall change in position,
taking into account only starting point and ending point
Units for displacement or distance - ANS-Meters
Distance - ANS-It is a measure of how far an object has traveled
Average speed - ANS-An object's total distance traveled divided
by the time elapsed
Units used for speed or velocity - ANS-Meters/second (m/s)
Average velocity - ANS-An object's displacement divided by time
elapsed.
Constant velocity - ANS-Velocity that remains unchanged
instantaneous velocity - ANS-The velocity of an object at an
specific point in time or at a specific point in the object's path
Average acceleration - ANS-The rate of change of velocity
divided by time elapsed.
Conversion factor - ANS-Multipliers that allow us to convert a
quantity expressed in one kind of unit into an equivalent value
expressed in another
Base unit - ANS-A fundamental unit of measurement that is
defined arbitrarily and not based on other combinations of units.
Examples from the SI System include meter, kilogram, liter,
second and kelvin.
Derived units - ANS-A unit created by combining base units
Imperial system - ANS-A system of units of measurement that is
primarily used in the United States and consists of units like the
pound, ounce, mile, and inch
International System of Units (SI) - ANS-A complete metric
system of units of measurement used by scientists that is based
on multiple of ten
Scientific Notation - ANS-A mathematical equation expression
used to represent a decimal number between 1 and 10,
multiplied by ten to a power of 10, so you can write large or small
numbers using less digit [Show Less]
