Scientific Method
What are the three main steps of the scientific method
Observing, Hypothesizing, Experimenting
a mathematical statement that two expressions are equal
equation
The SI base unit of time.
second
SI unit of force
Newton (N)
transfer of energy from one object to another by a force
work
the ability of other scientist to reach the same conclusion by performing the same experiment under different conditions.
reproducibility
weight
the study of motion and forces
Dynamics
diagram that represents the object and the forces on it without considering the causes of the forces or the reaction forces exerted by the object
free-body diagram
the use of science to solve practical problems
technology
An if/then statement in scientific reasoning
hypothetical proposition
The closeness of a measurement to the quantity's actual value
accuracy
the space relative to which motion is measured
frame of reference
What is the term for a free fall velocity at which the force of air resistance equals the objects weight?
terminal velocity
The minimum characteristics that a design must have to function are?
Criteria
Reasoning from specific evidence to a more general conclusion
inductive reasoning
How many significant digits are in 20,005
Five
the branch of physics that addresses the effects of forces on matter.
mechanics
An object that hangs from a fixed point and swings back and forth because of gravity
pendulum
The metric unit for one-thousandth
milli-
method of reasoning that involves the fact that a change in the value of one factor causes a predictable change in the value of another factor
method of concomitant variation
What quantity relates the density of a substance to the density of a standard substance?
specific gravity
An objects change in position
displacement
What causes an object to travel in a curved path rather than a straight line?
Centripetal force
For a STEM Project, Emma built several model cars with the exact shape proportions, and appearance as the cars they represented. What type of model did she build?
physical model
What fallacy occurs when a single term is ambiguously used with two different meanings in a single argument?
Equivocation
Name of the standard system of measurement universally used and accepted by scientists?
metric system
velocity
What type of friction affects stationary objects, preventing them from moving?
Static Friction
