Question 1 · 1 mark · Difficulty 2/3

An object will float if its density is:

  1. Less than the density of the fluid
  2. Greater than the fluid
  3. Equal to its mass
  4. Zero
Show answer & explanation
✓ Answer: ALess than the density of the fluid
An object less dense than the fluid displaces enough fluid to provide an upthrust equal to its weight, so it floats.
Question 2 · 1 mark · Difficulty 2/3

When an object is lowered into water, it appears to weigh less because of:

  1. The upthrust acting upwards
  2. Gravity disappearing
  3. Reduced mass
  4. The water's colour
Show answer & explanation
✓ Answer: AThe upthrust acting upwards
Upthrust acts upwards, partly supporting the object's weight, so it appears lighter when submerged.

AQA GCSE Physics: Upthrust and flotation FAQ

How many AQA GCSE Physics questions on Upthrust and flotation are there on Kramizo?
Kramizo currently has 15 exam-board-aligned practice questions on Upthrust and flotation for AQA GCSE Physics, with new questions added every week. Each question gives you instant feedback and a full examiner-style mark scheme that tells you exactly what would earn marks on a real AQA paper. The questions span the full difficulty range — from straightforward recall (level 1) right up to multi-step reasoning and evaluation (level 3) — so the bank works for first-pass revision and final exam-week stress testing alike.
Is Kramizo free for AQA GCSE students preparing for Physics?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Upthrust and flotation practice with other Physics topics or even switch to a totally different AQA subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Upthrust and flotation questions aligned to the official AQA GCSE Physics syllabus?
Every question is written against the published AQA GCSE Physics specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real AQA paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from AQA.
How is Upthrust and flotation typically tested on AQA GCSE Physics papers?
Upthrust and flotation appears across multiple question types on real AQA GCSE Physics papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
