The work done is directly proportional to both the force applied and the distance moved in the direction of that force. Since the force is horizontal and the box moves horizontally, the calculation is straightforward.
Tiada kerja dilakukan. Sebab: Walaupun daya dikenakan (otot tangan menahan berat beg), tiada sesaran berlaku ($s = 0 , \textm$. $$W = 50 , \textN \times 0 , \textm = 0 , \textJ$$ Since the force is horizontal and the box
Nota: Jawapan di atas adalah berdasarkan konsep umum buku teks KSSM. Sila rujuk nilai daya ( ) dan sesaran ( ) yang spesifik dalam buku teks anda.
For any work, energy, or power problem, follow these steps to ensure accuracy: $$W = 50 , \textN \times 0 ,
[ \textKomponen daya dalam arah gerakan = F \cos \theta ] [ W = (F \cos \theta) \times s ] [ W = (12 , N \times \cos 60°) \times 3 , m ] [ W = (12 , N \times 0.5) \times 3 , m ] [ W = 6 , N \times 3 , m = 18 , J ]
