Azhar realized that since the area of the hole (A₂) was much smaller than the area of the tank (A₁), the velocity of the water flowing out of the hole (v₂) must be much higher than the velocity of the water in the tank (v₁).
| Type | Example | Strategy | |------|---------|----------| | | Calculate the gravitational force between Earth & Moon. | Write known values → choose formula → substitute → unit check. | | Diagram‑based | Draw ray diagram for a convex lens at 2F. | Use two principal rays; label focal points & image characteristics. | | Experiment / SPS (Science Process Skills) | State hypothesis, identify manipulated/responding variables. | Follow scientific method: Aim → Hypothesis → Variables → Procedure → Conclusion. | | KBAT / Reasoning | Why do astronauts feel weightless even though gravity exists? | Apply concept of free fall & apparent weight. | fizik tingkatan 4 latihan
