IP Physics Notes (Upper Secondary, Year 3-4): 5) Pressure

Q: What does IP Physics Notes (Upper Secondary, Year 3-4): 5) Pressure cover?
A: Force-per-area basics, liquid columns, hydraulic systems, and Boyle's law for IP Y3-Y4 applied pressure questions.

Quick recap -- Pressure concentrates force over area. In fluids it scales with depth, density, and gravity; in gas systems it trades off with volume when temperature stays fixed.

Keep your practice loop tight via our IP Physics tuition hub-it links each topic here to quizzes, diagnostics, and WA-style problem sets.

Defining Pressure

• Pressure is force acting perpendicular to a surface per unit area.
• Formula: $$P = \frac{F}{A}$$
  • $P$ in $\pu{Pa} = \pu{N.m-2}$
