6short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.
What is pressure on a surface?Show answer
The same force over a smaller area gives a larger pressure. This is why a sharp knife (small area) cuts easily and why snowshoes (large area) stop you sinking into snow.
What are pressure in liquids?Show answer
A liquid exerts pressure on any surface in contact with it, and the pressure acts equally in all directions at a given depth.
What is the liquid pressure equation?Show answer
This explains why a dam is built thicker at the bottom, where the water pressure is greatest, and why deep-sea divers experience very high pressures.
What is q1?Show answer
State the equation for pressure on a surface and the unit of pressure. [2 marks]
What is q2?Show answer
A force of acts on an area of . Find the pressure. [2 marks]
What is q3?Show answer
State two factors that affect the pressure at a point in a liquid. [2 marks]
