2. Physics is science concerning matter and
energy, and their relationship with each
other, it is experimental being studied by
physicist by performing experiments to test
various physical hypotheses. It could be
affirming a discovery or disproving an
outdated knowledge.
3. In Physics, we use these physical quantities
in describing an object properties.
These quantities are as follows:
1. Length- is a quantity that shows
dimension,; how far, how long how thick and
how high
4. 1. Length- is a
quantity that
shows
dimension,;
how far, how
long, how thick
and how high
5. 2. Mass- it tells
us how much
stuff there is in
the object, how
heavy it is.
6. 3.Electric current-
it tells us how
much electrons,
tiny particles with
negative charge
are passing
through per unit
10. 7. Time- it tells
us how much
was change in
an instance
11. We give credence to physical
quantities by affixing them with
these things. Can you see it?
We use UNITS to define
quantities. A unit is a
quantity chosen as a
standard so we can express
how much was in an object,
how far we are and so on.

14. TWO TYPES OF MEASUREMENT
Pride itself foe consistency
and easy to use. This
system employs the base
10 computation so that it
will be easier to convert
between units
Prides itself in a long
history. The people back
then has no standardized
way of measuring, so
they have to improvise.

METRIC
SYSTEM
15. The English or Imperial System is a unit
system that was created in Great Britain
that unified various standards of
measurement across entire country. This
system was developed by the creative
minds of early natural philosophers and
apothecaries or pharmacists.
16.
17. The International or Metric System is a
unit system designed to simplify the
way things are measured, due to the
inconsistency of the units used in the
English System way before they were
unified. Even Great Britain and the US
adopted this system.
21. Conversion- adoption of value whose
empiricism in its original form (dollar to
peso)
we convert units in one system to anther
so that we can use them better
22. Mario wants carpet that is 18 feet long, but
the vendor quotes all prices in inches. How
many inches long does the carpet need to
be?
23. Mario wants carpet that is 18 feet long, but

be?
26. RULES AND GUIDELINES IN WRITING SCIENTIFIC NOTATION
Scientific Notation is a way scientists compress extremely large or small numbers into
manageable values widely understood by many. Although there are numbers that do not
need such configurations, such as 125 or 0.12, scientific notation enables scientists to
read and organize values that can help in their research.
Writing numbers in scientific notation has two (2) advantages:
1.It saves space, especially when handling extremely large amounts of data using
complicated formulae.
2.It allows for faster unit conversions.
Guidelines on how to write in Scientific Notation.
1. Coefficient must be greater than or equal to one (1), but less than 10, for there
must be only one (1) nonzero digit.
Example:
1.23 × 1023 This is CORRECT.
12.3 × 1022 This is WRONG.
0.123 × 1024 This is also WRONG.
27. 2.The base is always 10.
3.Exponents in the scientific notation represent the number of digits the
decimal point has crossed, and are either positive or negative only.
a.The exponent is POSITIVE if the decimal point moves to the left. This
means that the number has a large value (see Example a).
b.The exponent is NEGATIVE if the decimal point moves to the right.
This means that the number has a small value (see Example b).
c.Although fractional exponents represent radical values, there is no
radical notation in the scientific notation.
Example A:
a.1.23 × 1023 is 123,000,000,000,000,000,000,000 when expanded.
28. b.1.23 × 10−23 is
0.0000000000000000000000123 when
expanded.
Operations involving Scientific Notations are
straightforward. This method utilizes the basic
four (4) operations of Mathematics when
handling decimal and exponent values.
30. Definition of Terms
a. Variables refer to a set of data gathered and
observed over the experiment. There are several
kinds of variables, each one influencing the other.
A variable is a characteristic that can be measured
and that can assume different values. Height, age,
income, province or country of birth, grades
obtained at school and type of housing are all
examples of variables.
31. b.Axes are the projections of the Cartesian plane
that denote and track changes within the
observable period of the experiment or research.
32. i.The X-axis is the horizontal part of the
Cartesian plane that usually represents the
independent variable,
ii.The Y-axis is the vertical part of the
Cartesian plane that represents the dependent
variable.
33. c. A Curve is a linear representation of the
trend that the variables show.
d. An Asymptote is a trend line that lies exactly
close to one of the axes, but never touches it.
34. e.A Cusp is a singular point
on a curve wherein a moving
point starts to move
backward.
f.An Inflection Point is a point
in a curve wherein the
curvature changes.
