Introduction to Physic
Vector quantity
-Physical quantities that have magnitude and direction -Momentum -Acceleration -Force -Pressure -Velocity
Scalar quantity
-Physical quantities that have magnitude only -Length -Time -Temperature -Mass -Speed -Area -Volume -Density -Distance -Work -Energy
Deviation
Difference in measured value and its mean value
Question #1
Answer #1
Graph #1
Directly proportional
Graph #3
Inversely proportional
Accuracy
Kena target
Graph #2
Linearly proportional
Zero error in vernier calliper
Main scale - 0.1 cm (kira yg suda limpas vernier) Vernier scale - 0.01 cm (kira yg selari dngn garis main scale)
Sensitivity of measuring instruments
Measuring length
Graph #4
Non-linear
Derived quantities
Physical quantities derived from combinations of base quantities through multiplication or division or both
Base quantities
Physical quantities that cannot be defined in terms of other physical quantities
Zero error
Pointer of the instrument does not return to zero when it is not being used
Sensitivity of voltmeter
Scale division yg lebih kecil lbih sensitivity

Parallax error
The error that occurs when your eye is not at the same height as the liquid
Systematic error
Values either all higher or all lower than actual value
