SOLUTION
⩥ mathematical model. Answer: treat physical objects or phenomena
using mathematical methods. In these models, pertinent physical
characteristics are represented using formulas, graphs, or other
mathematical means. For example, the mathematical model below
models the wavelength and amplitude of a wave.
⩥ computer model. Answer: are becoming increasingly important in
explaining and predicting natural phenomena, such as weather patterns
and the detailed movements of objects in the solar system
⩥ principle of falsification. Answer: is that only falsifiable statements
can be subject to scientific inquiry. A statement such as "a rock falls
because invisible demons pull it down" is not falsifiable, because no
conceivable experiment or observation could prove that invisible
demons are not pulling it.
⩥ Hypothesis. Answer: is a testable statement about how something in
nature works. It is typically the best tentative assumption that
,researchers can make based on the evidence they already have at that
point.
⩥ Theory. Answer: is a statement that explains a wide range of
observations and that is supported by a large body of scientific evidence.
It explains how and why things happen
⩥ Law. Answer: is a concise statement that is supported by scientific
evidence and repeated experiments and describes a widespread pattern in
nature. Laws are intended to be universal.
⩥ scientific investigation. Answer: scientific ideas must be testable.
Scientists test their ideas with a variety of different types of
investigations. Some scientists work in laboratories, performing
controlled experiments. Others may observe distant stars and come up
with theoretical models to explain their observations. Other scientists
engage in field studies.SI system-As scientific investigations became
more widespread and global, scientists recognized the need for a
universal, consistent system of measurement units. This universal
system would allow scientists around the world to easily share and
compare their data.
⩥ base quantities. Answer: seven physical quantities are designated as
base quantities
, ⩥ time. Answer: measures how long an even lasts or the break between
evens. It also lets us order events from the past through the present and
into the future. The base unit of time is a second, abbreviated as s.
⩥ Length. Answer: is used to describe the distance between two objects
or to describe two ends of an object. The base unit is m
⩥ Mass. Answer: used to describe the amount of matter in an object. The
base unit for mass is kg
⩥ Temperature. Answer: Tells us how hot something is. It is essentially a
measure of how fast the particles of a substance are moving. The base
unit of temperatue is kelvin abbreviated as K. derived units-when base
quantities are combined.
⩥ triple. Answer: beam balance-used to measure mass
⩥ graduated cylinder. Answer: liquid is typically measured in a
graduated cylinder
⩥ direct relationship. Answer: between two variables exists when an
increase of one variable results in an increase of the other, or a decrease
of one results in a decrease of the other. For example, assuming you
maintain a constant speed, the distance your car travels is directly related
to the time of travel.
