1A runner moves at 4 m/s for 15 s. What distance is covered?
A.60 m
B.19 m
C.3.75 m
D.11 m
Explanation: Distance = speed × time = 4 m/s × 15 s = 60 m.
2A car accelerates uniformly from rest to 20 m/s in 5 s. What is its acceleration?
A.4 m/s²
B.100 m/s²
C.0.25 m/s²
D.15 m/s²
Explanation: Acceleration = Δv/Δt = (20 − 0)/5 = 4 m/s².
3Which is the SI unit of force?
A.The newton (N)
B.The joule (J)
C.The watt (W)
D.The pascal (Pa)
Explanation: Force is measured in newtons (N), where 1 N = 1 kg·m/s². The joule is energy, the watt is power, the pascal is pressure.
4A force of 10 N acts on a 2 kg object. What is the acceleration? (Use F = ma.)
A.5 m/s²
B.20 m/s²
C.0.2 m/s²
D.8 m/s²
Explanation: From F = ma: a = F/m = 10/2 = 5 m/s².
5What is the weight of a 5 kg mass on Earth? (g ≈ 10 m/s².)
A.50 N
B.5 N
C.15 N
D.2 N
Explanation: Weight = mg = 5 × 10 = 50 N. Mass (kg) and weight (N) are different quantities.
6A block of mass 3 kg is pushed with 12 N of force across a frictionless surface. What is its acceleration?
A.4 m/s²
B.36 m/s²
C.0.25 m/s²
D.9 m/s²
Explanation: a = F/m = 12/3 = 4 m/s². With no friction the net force equals the applied force.
7How much work is done lifting a 2 kg book 1.5 m upward? (g ≈ 10 m/s².)
A.30 J
B.20 J
C.15 J
D.3 J
Explanation: Work = force × distance = mg × h = (2 × 10) × 1.5 = 30 J.
8A machine does 600 J of work in 30 s. What is its power output?
A.20 W
B.18000 W
C.0.05 W
D.570 W
Explanation: Power = work/time = 600/30 = 20 W.
9What is the kinetic energy of a 2 kg object moving at 3 m/s? (KE = ½mv².)
A.9 J
B.6 J
C.18 J
D.3 J
Explanation: KE = ½ × 2 × 3² = ½ × 2 × 9 = 9 J.
10In a vacuum, a heavy ball and a light ball are dropped from the same height. Which lands first?
A.They land together
B.The heavy ball
C.The light ball
D.Neither ever lands
Explanation: In a vacuum, with no air resistance, all objects accelerate at g regardless of mass, so they land together (Galileo's result).

About the Osaka Public High School Entrance Examination — Science Exam

The Osaka Prefectural Public High School Entrance Examination in Science (理科) tests lower-secondary graduates on physics, chemistry, biology and earth science (第1分野 and 第2分野). In the 令和8年度 (2026) cycle the general academic test (一般入学者選抜 学力検査) covers five subjects (国語, 社会, 数学, 理科, 英語), each worth 90 points (total 450), all sat on a single day on 11 March 2026 (1st 国語, 2nd 数学, 3rd 英語 with リスニング, 4th 理科, 5th 社会), with 合格発表 on 19 March 2026. The paper is aligned to the MEXT junior-high Course of Study (平成29年 中学校学習指導要領 理科編) and tests 知識・技能 plus 思考力・判断力・表現力, with constructed-response items including 計算 (Ohm's law, density, work/power), 実験考察, 作図 (force/ray diagrams), and 結果記述. Unlike 国語・数学・英語, the 理科 paper has no tier system — all schools use the same single common paper. All prefectural schools use the common board-set paper; no school sets a self-made 理科 paper. Selection combines 学力検査 450 + 調査書 450 (中3 ×6, 中1・中2 ×2) into a 900-point 総合点 using a school-chosen 倍率タイプ (I–V); the top 110% form (Ⅰ)群, the top 90% of those are admitted, and the (Ⅱ)群 ボーダーゾーン is decided against each school's アドミッションポリシー. Since FY2014 (平成26年度) all Osaka prefectural public high schools form a single prefecture-wide school district (全府一学区 / 府内全域). There is no single prefecture-wide pass line.

Assessment

40-minute paper worth 90 points, aligned to the MEXT 理科 Course of Study with constructed-response items including 計算 (Ohm's law, density, work/power), 実験考察, 作図 (force/ray diagrams), and 結果記述. It is sat in the 4th period on 11 March 2026. The five academic-test subjects (国語, 社会, 数学, 理科, 英語) each carry 90 points for a maximum of 450 points. The paper tests 知識・技能 plus 思考力・判断力・表現力. Unlike 国語・数学・英語, the 理科 paper has no tier system — all schools use the same common paper. It contains no 小問集合: four 大問 cover 物理, 化学, 生物 and 地学 one apiece, weighting the four fields about equally, each presented as a long experiment- or observation-based passage.

Time Limit

40 minutes. The 理科 paper is sat in the 4th period on 11 March 2026; the full academic test is a single day — 1st 国語, 2nd 数学, 3rd 英語 (with リスニングテスト), 4th 理科, 5th 社会.

Passing Score

No fixed pass mark. Admission is decided by each school using a 総合点 out of 900: 学力検査 450 (5 subjects × 90) plus 調査書 450 (中3 評定 ×6, 中1・中2 評定 ×2), each multiplied by the school's chosen 倍率タイプ from types I–V (I: 1.4/0.6; II: 1.2/0.8; III: 1.0/1.0; IV: 0.8/1.2; V: 0.6/1.4). The top 110% of applicants form (Ⅰ)群; the top 90% of those are admitted; the remaining (Ⅱ)群 (ボーダーゾーン) is decided against the school's アドミッションポリシー using the 自己申告書 and 活動記録. There is no single prefecture-wide pass line.

Osaka Public High School Entrance Examination — Science Study Tips from Top Performers

1Drill the core physics calculations — Ohm's law (V=IR), density (ρ=m/V), work (W=Fs), power (P=W/t) and kinetic energy (½mv²) — to fluency, since the 計算 items reward fast unit-consistent arithmetic under the 40-minute limit.
2Memorise the MEXT 第1分野 reaction types (metal + acid → salt + H₂, thermal decomposition, neutralisation) and the pH/indicator colour table, then practise balancing simple equations and identifying ions from the products.
3Practise 実験考察 items by identifying the independent/dependent/control variables and predicting the graph shape before reading the options, since experiment-design questions recur across physics and biology.
4Build a one-page summary of biology pathways — photosynthesis and respiration equations, gas exchange, and the inheritance (DNA base-pairing, Mendel's laws, Punnett-square ratios) — and quiz yourself on the key numbers (3:1, 9:3:3:1).
5For earth science, link the rock cycle, plate-tectonic boundaries and the atmosphere/season diagrams to observable phenomena (earthquakes, volcanoes, seasons) rather than memorising isolated facts.
6Time your practice under the 40-minute limit and attempt the physics 計算 and chemistry knowledge items first to bank marks before the longer 実験考察 and 結果記述 items.

Frequently Asked Questions

Is this question bank the same as the real Osaka 理科 exam?

No. The official paper is written in Japanese with constructed-response items including 計算 (Ohm's law, density, work/power), 実験考察, 作図 (force/ray diagrams), and 結果記述. This bank is an English-language multiple-choice study adaptation of the same syllabus content and cannot replace writing out your own working and explanations.

How long is the Osaka 理科 paper and what is it worth?

It lasts 40 minutes and is scored out of 90 points, one of five subjects that together total 450 points (each subject 90 points). 理科 is sat in the 4th period on 11 March 2026.

Does the 理科 paper have difficulty tiers like 国語・数学・英語?

No. For 国語・数学・英語 the board sets three tiers (基礎的/標準的/発展的) and each school selects one, but 理科 and 社会 use a single common paper sat by all schools — there is no tier system for science.

How is the selection structured in 2026?

Osaka combines the academic test (学力検査, 450 points) with the report card (調査書, 450 points, 中3 ×6 and 中1・中2 ×2) into a 900-point 総合点 using a school-chosen 倍率タイプ from types I–V (I: 1.4/0.6, II: 1.2/0.8, III: 1.0/1.0, IV: 0.8/1.2, V: 0.6/1.4). The top 110% form (Ⅰ)群, the top 90% of those are admitted, and the (Ⅱ)群 ボーダーゾーン is decided against each school's アドミッションポリシー. There is no prefecture-wide pass line.

How much is the examination fee?

The 入学検定料 (entrance examination fee) for an Osaka prefectural public high school is ¥2,200 for the 全日制 (full-time) course, ¥950 for the 定時制 (part-time) course and ¥800 for the 通信制 (correspondence) course, paid via the online 出願システム. A separate 入学料 (¥5,650 full-time) is due after acceptance. It is paid once for the whole five-subject 学力検査, not per subject paper.

When was the 2026 paper sat and when were results announced?

The 令和8年度 学力検査 was held on a single day, 11 March 2026 (1st 国語, 2nd 数学, 3rd 英語 with リスニング, 4th 理科, 5th 社会), with 合格発表 on 19 March 2026 via the online 出願システム.
