MEASUREMENT
LEARNING OBJETIVES
∙Solve measurement
problems involving
conversion of units,
expression of
measurements in scientific
notation.
PHYSICS
The word physics itself is derived from
the Greek word, φuσισ (phusis)
meaning nature or natural things.
defined as the science of matter,
motion, energy and
their interactions.
Study of matter and its motion
through time and space.
Helps us analyze the behavior of
nature around us.
MEASUREMEN
T
the determination of the size or
magnitude of something
can also be defined as
"Comparison of an unknown
quantity with some known
quantity of the same kind".
PHYSICAL
QUANTITY
are a characteristic or property
of an object that can be
measured or calculated from
other measurements
any number that is used to
describe quantitatively a
physical phenomenon
The
Fundament
al
Quantities
of
Mechanics
MASS - is the quantity of matter in a
physical body.
LENGTH - the distance from one
end of something to the other end a
measurement of how long something
is
TIME - it refers to the number of
years, days, minutes, etc.
Representing such an interval
Derived
Quantities
These are the quantities obtain
from the Fundamental quantities
Examples:
1. Velocity
2. Acceleration
3. Energy
4. Area
5. Volume
SYSTEM
OF UNITS
S.I. / METRIC SYSTEM – refers to the
International System of Units. It
provides a complete coherent system
of units used for physical quantities.
Length – meter (m)
Mass – gram (g)
Time – second (s)
BRITISH UNITS – are used only in
mechanics and thermodynamics
Length – feet (ft)
Mass – slug (slug)
Time – second (s)
TABLE OF
PREFIXES
CONVERSION FACTORS/
UNITS
EXAMPLES
1. How many
inches are
there in 10
meters?
2. The speed of a car as
measured by a speedometer
is 62 kilometers per hour
(km/h). Convert this unit to
centimeter per second (cm/s)
3. How many yards
are there in 1km?
FIRST 4
Examples
Let’s test your knowledge about metric units of distance
measurement and your ability to convert between these.
1. What is longer, 2.16 m or 216 mm?
2. How many millimeters are in 27. 1 centimeters?
3. Chleo grew 10 centimeters in 1 year. She is now 1.6 m tall.
How tall was she 1 year ago?
4. Nedy buys a reel of thread for sewing. There are 10 m of
thread on the real. She uses 210 cm. How much is left on the
reel in centimeters?
5. How many minutes are in four hours?
Examples
1. How many pounds does 2.00 kg of cheese weigh?
2. How many mL are in 0.50 quarts?
3. How many inches are in 1.00 km?
4. How many feet are in 3.45 km?
5. How many km are in 5.00 miles?
6. How many yards are in 72.5 miles?
7. How many cc's are in 979 mL?
8. How many Kelvins are in -15.5oC?
9. How many degrees Celsius are in 315 K?
10.How many degrees Fahrenheit are in 30.0oC?
Quiz #1
Quiz #1 : Part I
1. Reynalda wants to send a box of oranges to a friend by mail. The box of
oranges cannot exceed a mass of 10 kg. If each orange has a mass of 200g,
what is the maximum number she can send?
2. Jeffrey is overweight. He is 105 kg. His aim is to lose 500 g per week. If he
manages this, how many weeks will it be until he is 90 kg?
3. A 30 g serving of a certain breakfast cereal has 0.5 g of salt. How much salt
would that be in milligrams?
4. 3.28 ft = _______m
Quiz #1 Part II: Fill in the blanks with the correct
conversion and scientific notation. Answer the
succeeding questions.
Cholo and her sister Chloe went to amusement park to ride a roller coaster.
The distance of the park from their house is about 278 km which is also equal
to 1.) ______ miles and that can be express as 2.) _________ in scientific
notation. They ride on their car heading to a park for about 1.26 hours which
is equal to 3.)_________minutes. Converting that time into seconds it takes
them 4536 second which may express as 4.) ___________ in scientific
notation. Their car run 221km/hr. what will be the speed of the car if this will
be converted into cm/s? Express your answer in correct scientific notation.
(5.) Upon reaching the park they went straight to the roller coaster. It
measures 456 ft tall and has a length of 8133 ft. Its speed is 149 miles per
hour. Convert the height (6.) and length (7.) of the roller coaster to meters and
convert the speed to meters per second (8.). Express your answer in correct
