計算機規定
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: AO1: Knowledge and understanding of physics (35%)
AO2: AO2: Application of knowledge and understanding of physics (40%)
AO3: AO3: Experimental skills and investigative capabilities in physics (25%)
根據歷屆試題與評分準則整理（2023–2026）。
計算機程式
Graph: zeros, intersections & turning points
Graphical calculator / GDC (exam mode)
用途: Plot a function to read its roots (zeros), points of intersection, and maxima/minima.
使用時機: Checking solutions, sketching, or solving where an analytic method is hard.
步驟
Graph the function(s) and use the built-in zero, intersect and maximum/minimum tools.
考試提示: Allowed, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
Numerical equation solver
Graphical calculator / GDC (exam mode)
用途: Solve an equation or find a variable numerically when an algebraic route is long or implicit.
使用時機: Iterative or implicit equations, or to confirm an algebraic solution.
步驟
Use the equation/zero solver, entering the equation and a sensible starting estimate.
考試提示: Allowed, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
Numerical integration & differentiation
Graphical calculator / GDC (exam mode)
用途: Evaluate a definite integral \(\int_a^b f(x)\,dx\) or a gradient \(f'(x)\) at a point.
使用時機: Checking calculus answers, or where only a numerical value is needed.
步驟
Use the GDC's numeric integral / derivative function with the limits or the point.
考試提示: Allowed, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
Statistics & probability distributions
Graphical calculator / GDC (exam mode)
用途: 1-var/2-var statistics, linear regression, and cumulative binomial / normal / Poisson probabilities without tables.
使用時機: Statistics questions and hypothesis tests.
步驟
Enter data in the statistics editor, or use the distribution menu (binomial cdf, normal cdf, …).
考試提示: Allowed, but clear stored programs/data (graphical calculators in exam mode) and show the required working — unsupported calculator answers score no method marks.
常見錯誤
1high涉及分數: 3Materials
Failing to convert Young Modulus or material stress values from GPa or MPa to Pa, leading to severe order-of-magnitude errors.
如何避免: Multiply GPa values by 10^9 and MPa values by 10^6 before performing any algebra or calculation steps.
2high涉及分數: 4Mechanics
In projectile motion, using the vertical acceleration (g) in horizontal distance calculations, or treating horizontal velocity as variable.
如何避免: Keep horizontal components (constant velocity, zero acceleration) completely separate from vertical components (SUVAT with g = 9.81 m/s^2 downwards).
3medium涉及分數: 2Waves and Particle Nature of Light
Failing to divide the total round-trip travel time by two in pulse-echo / ultrasonic distance calculations.
如何避免: Identify reflection scenarios (ultrasound, sonar, radar) and write down t_one_way = t_total / 2 as your very first step.
4medium涉及分數: 3Mechanics
Taking moments about a pivot on a uniform door or bar and forgetting to halve its total width to locate the center of gravity.
如何避免: Always locate the weight of a uniform object at exactly half its physical length (L/2) when setting up the principle of moments.
5high涉及分數: 3Materials
When analyzing a falling sphere to find terminal velocity or viscous drag, omitting the fluid upthrust force from the force balance.
如何避免: Apply Newton's first law for terminal velocity: Viscous Drag + Upthrust = Weight. Drag is not equal to Weight alone unless upthrust is explicitly stated as negligible.
6high涉及分數: 2Materials
Drawing a forced line of best fit through the origin (0,0) in Unit 3 graphing when the raw experimental data has a clear non-zero intercept.
如何避免: Never force a line of best fit through the origin unless theoretical physics dictates it. Follow the natural distribution of your plotted points.
