half 1st lesson

Question 1

resolve from the experimental to take the same measurement in exactly the same way to take number

Answer 1

random error

Question 2

It refers to the closeness of the measurements to the true or accepted value

Answer 2

accuracy

Question 3

It refers to the closeness of the measurements of the results to each other.

Answer 3

precision

Question 4

that are consistently the same interaction (hanggang mag simula hnggng matapos nandon)

Answer 4

systematic error

Question 5

types of experimental error

Answer 5

systemic
random

Question 6

Common sources of error in physics laboratory experiments

Answer 6

•Incomplete definition (may be systematic or random)
• Failure to account for a factor (usually systematic)
• Environmental factors (systematic or random)
• Instrument resolution (random)
• Calibration (systematic)
• Zero offset (systematic)
• Physical variations (random)
• Parallax (systematic or random
• Lag time and hysteresis (systematic)
• Instrument drift (systematic)

Question 7

if ure going to have a experiment, u need to consider the air resistant. mas babagal ung object na huhulog

Answer 7

Failure to account for a factor (usually systematic)

Question 8

ex: hinihila mo ung string tas ung isa hindi

Answer 8

incomplete definition (systematic or random)

Question 9

ex: tinitingnan muna ung temperature. if u want to test ung headset hindi ka pwede mag test sa maingay dapat sa napaka quiet na place para makita ung tunog

Answer 9

environmental factors (systematic or random)

Question 10

if they want to check it more accurate mas mataas pa ung ginagamit

Answer 10

Instrument resolution (random)

Question 11

kailangan pantay, even if using calibration

Answer 11

Calibration (systematic)

Question 12

kailangan mga naka tapat sa zero

Answer 12

Zero offset (systematic)

Question 13

paulit ulit na ginagawa at dapat makakalapit

Answer 13

Physical variations (random)

Question 14

observer, between the observer eye. malaki ung apekto ng measurement

Answer 14

parallax systematic or random

Question 15

ito ung memory na matagal. mabagal ung system especially using computer

Answer 15

Lag time and hysteresis (systematic)

Question 16

pagiging careless or poor technique

Answer 16

personal driff

Question 17

The _____ and _____ of a measuring system leads to uncertainty

Answer 17

accuracy and precision

Question 18

A device can repeated get the same measurement (____), but always be wrong (____)

Answer 18

precise, not accurate

Question 19

○ Used to reflect uncertainty in measurements

Answer 19

• Significant Figures

Question 20

can be specified completely by giving a single number and the appropriate unit.

Answer 20

Physical quantities
