计算器规定
A scientific or graphical calculator is permitted. Graphical calculators must be in exam mode with all stored programs and data cleared before the exam; the calculator must not be able to retrieve stored text or formulae.
AO1: Knowledge and understanding of physics (40%)
AO2: Application of knowledge and understanding, analysis and evaluation of physics (40%)
AO3: Experimental skills, analysis and evaluation of data and methods in physics (20%)
根据历届试题与评分标准整理（2023–2025）。
计算器程序
Table mode for roots & turning points
Scientific calculator (e.g. Casio fx-991 series)
用途: Tabulate \(y\) across a range of \(x\) to locate sign changes (roots) and approximate maxima/minima.
使用时机: Solving or sketching a function when you want to find where its graph crosses or turns.
步骤
Enter the function in TABLE mode, set the start, end and step, then read where the sign of \(y\) changes or where it peaks.
考试提示: Allowed, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
Statistics mode (mean, SD & regression)
Scientific calculator (e.g. Casio fx-991 series)
用途: Read the mean \(\bar{x}\) and standard deviation directly, and the gradient/intercept (and \(r\)) of a linear regression for bivariate data.
使用时机: Any data-handling, statistics, or required-practical analysis question.
步骤
Enter the data in STAT mode (1-VAR or A+BX), then recall \(\bar{x}\), \(\sigma\) or the regression coefficients.
考试提示: Allowed, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
Carry exact values with Ans & memory
Scientific calculator (e.g. Casio fx-991 series)
用途: Keep full-precision intermediate values to avoid rounding errors.
使用时机: Multi-step calculations where premature rounding loses the final accuracy mark.
步骤
Use Ans, STO/RCL or the M+ memory to reuse the unrounded result of each step; round only the final answer.
考试提示: Allowed, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
Equation solver — to CHECK your working
Scientific calculator (e.g. Casio fx-991 series)
用途: Use the built-in EQN/SOLVE mode to verify roots of quadratics or simultaneous equations you have already solved by algebra.
使用时机: As a check only, after solving by hand.
步骤
Enter the coefficients in EQN mode (or use SOLVE) and confirm they match your worked solution.
考试提示: Allowed, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
常见错误
1high涉及分数: 2Forces, movement, shape and momentum
Defining elastic behavior simply as 'returning to original shape' when a force is applied, omitting the critical limit condition.
如何避免: Define elastic behavior as the ability of a material to return to its original shape and length *only after* the applied load or deforming force is removed.
2high涉及分数: 4Ideal gas molecules
Failing to convert Celsius temperatures to Kelvin when performing gas law calculations.
如何避免: Always add 273 to the Celsius temperature (e.g., 16°C + 273 = 289 K) before substituting values into the pressure law or Boyle's law equations.
3high涉及分数: 2Fission and fusion
Confusing the physical roles of control rods and the moderator in a nuclear fission reactor.
如何避免: Explicitly state that control rods *absorb* neutrons to control the reaction rate, while the moderator *slows down* fast-moving neutrons to sustain the chain reaction.
4high涉及分数: 1Forces, movement, shape and momentum
Leaving mass values in grams rather than converting them to kilograms when calculating kinetic energy, gravitational potential energy, or momentum.
如何避免: Check the given unit. If mass is in grams (e.g., 159 g), divide by 1000 to convert to kilograms (0.159 kg) before using physical formulas.
5high涉及分数: 2Radioactivity
Using the word 'atoms' instead of 'nuclei' when defining nuclear fission, fusion, or radioactive decay.
如何避免: Ensure you refer strictly to 'nuclei' or 'nucleus'. For example: 'Fission is the splitting of a heavy nucleus into two smaller daughter nuclei.'
6medium涉及分数: 2Light and sound
In speed of sound echo experiments, failing to double the distance when using the speed equation.
如何避免: Because sound travels to the obstacle and back, the total distance traveled is 2d. Use the formula: speed = (2 * distance) / time.
7high涉及分数: 3Electromagnetism
Drawing crossing, overlapping, or non-parallel magnetic field lines in uniform field diagrams.
如何避免: Draw uniform magnetic fields as straight, parallel, equally spaced lines with clear arrows pointing from North to South. Lines must never cross or touch.
8high涉及分数: 1Energy and voltage in circuits
Leaving current values in milliamperes (mA) instead of converting them to amperes (A) in electrical equations.
如何避免: Divide the mA value by 1000 (e.g., 2.4 mA = 0.0024 A) before substituting it into equations like V = IR or P = IV.
