The Scientific Method
What format do we prefer hypothesis to be stated in?
“If...then...because”
How many significant digits are in this number? 0.005030

Two types of friction
Static and Kinetic
The variable being tested and measured in a scientific experiment. Usually in the "then" portion of the Hypothesis
Dependent variable
What is the conversion factor - meters to kilometers?
1 km / 1000 m
9.8 m/s^2
Gravitational acceleration
The group of test subjects that are introduced to the test variable/procedure
Experimental Group
Multiplying with scientific notation, True or False: The coefficients must be the same
FALSE
Force perpendicular to the surface
Normal force
What is a hypothesis?
An educated guess that is a proposed explanation for an observation - a statement
Define the 3 components of correct scientific notation
Coefficient, base, exponent
True or False: how fast an object is moving effects the coefficient of friction
FALSE
