Kuantiti Skalar dan Kuantiti Vektor

Kuantiti Skalar

1. Kuantiti skalar ialah kuantiti fizik yang mempunyai magnitud sahaja.
2. Magnitud ialah nilai berangka kuantiti tersebut. 
3. Contoh-contoh kuantiti skalar ialah jarak, laju, jisim, isipadu, suhu, ketumpatan dan tenaga.

Kuantiti Vektor

1. Kuantiti vektor ialah kuantiti fizik yang mempunyai kedua-dua magnitud dan arah. 
2. Contoh-contoh kuantiti vektor ialah sesaran, halaju, pecutan, daya dan momentum.

Contoh:
Asingkan kuantiti-kuantiti fizik berikut kepada kuantiti skalar atau kuantiti vektor.
Categorize each quantity below as being either a vector or a scalar.

Laju, halaju, pecutan, jarak, sesaran, cas elektrik, ketumpatan, isipadu, panjang, momentum, masa, suhu, daya, jisim, kuasa, kerja, impuls.
Speed, velocity, acceleration, distance, displacement, energy, electrical charge, density, volume, length, momentum, time, temperature, force, mass, power, work, impulse. 

Jawapan:

Kuantiti skalar: laju jarak tenaga cas elektrik ketumpatan isipadu panjang masa suhu jisim kuasa kerja Kuantiti Vektor halaju pecutan sesaran momentum  daya impuls

Scalar Quantities: speed  distance  energy  electrical charge  density  volume  length  time  temperature  mass  power  work Vector Quantities velocity  acceleration  displacement  momentum  force  impulse

English Notes:

Scalar Quantity

1. Scalars are quantities which are fully described by a magnitude alone. 
2. Magnitude is the numerical value of a quantity. 
3. Examples of scalar quantities are distance, speed, mass, volume, temperature, density and energy. 

Vector Quantity

1. Vectors are quantities which are fully described by both a magnitude and a direction. 
2. Examples of vector quantities are displacement, velocity, acceleration, force, momentum, and magnetic field.
