Dalam Fizik, hanya berlaku jika dua syarat dipenuhi:

$$W = F \times s$$ $$W = 20 , \textN \times 5 , \textm$$ $$W = 100 , \textJ$$

), indicating that the extension is directly proportional to the force applied ( ), which is consistent with Hooke's Law. 2. Determining the Gradient The gradient ( graph represents the (

In Aktiviti 1.3 of the textbook (Chapter 1: Measurement), the primary focus is on analyzing graphs and calculating work done (kerja) through the area under a force-extension graph.
