Resolution of a Force
 
A force is a vector quantity which has both magnitude (size) and direction. Thus, the operations (for example, addition and subtraction) carried out on forces are not merely taking two numbers and adding / subtracting them. As directions are involved, angles have to be taken into consideration when performing operations on forces (and other vector quantities).

The resolution of a
force is the separation of a single force into its components with different directions - usually perpendicular to one another. The resolution (separation) of a force into its components facilitates (helps in) the computations / calculations needed to be carried out.

Very often, trigonometry is used to help resolve
forces into their components.

Consider the following:

The object (block) of mass, m,  is resting on a horizontal plane. The object has the
force of gravity (weight, W = mg) acting upon it. Weight is a force that acts directly straight down to the centre of the Earth - a vector quantity represented by the red arrow.

Resolusi / Peleraian Daya

     
Daya merupakan kuantiti vektor yang mempunyai magnitud dan arah. Justeru itu, operasi (seperti hasil tambah dan hasil tolak) yang dilakukan ke atas daya bukan semata-mata mengambil dua nombor dan menjalani proses campur atau tolak. Oleh kerana arah perlu dipertimbangkan, sudut-sudut perlu diambil kira apabila melakukan operasi ke atas daya (dan kuantiti-kuantiti vektor yang lain).

Resolusi
daya merupakan peleraian satu daya kepada komponen-komponennya dalam arah berlainan - lazimnya pada arah bersudut tepat dengan satu sama lain. Resolusi (peleraian) daya kepada komponen-komponennya memudahkan pengiraan / komputasi yang perlu dilakukan.

Biasanya
trigonometri digunakan untuk membantu meleraikan daya kepada komponen-komponennya.

Apabila sebuah objek diletakkan pada satah mendatar, ia akan mengalami
daya graviti (berat, W = mg). Berat merupakan daya yang bertindak secara menegak - terus ke arah pusat Bumi.
