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

Consistency

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
