如何準備 AP Physics C: Mechanics
強化微積分基礎
AP Physics C: Mechanics 的許多概念需要使用到微積分,比如透過 differentiation 尋找速度函數。
理解物理原則
理解牛頓定律、力平衡、力矩平衡、能量守恆、動量守恆等核心概念。
規律練習解題
完成各種類型的習題,特別是自由作答題,能幫助你增強分析與解決複雜問題的能力。
強化實驗能力
實驗對物理學至關重要,如果你有實際操作的經驗,許多題目將會更得心應手。
利用學習資源
使用可信的學習資源能幫助你更高效地學習,比如使用 AP Physics C 參考書(如 Princeton Review 或 Barron’s)和網路資源(如 Khan Academy)。
進行模擬測驗
模擬考試能讓你熟悉考試格式並提高時間管理能力。
參加家教或補習班課程
跟著有經驗的人學習、練習,能夠少走許多彎路,也能對時間進行更有效率的分配。
AP Physics C: Mechanics 是一門具有挑戰性的課程,如果你選了這門課,代表你有很大的野心,也代表你對於自己的未來有一定程度的規劃。雖然有挑戰性,但只要透過有效的準備與規律的練習,取得高分就不會太難。希望這篇文章能幫助你更了解這一門課程,也能帶給你更多信心!
考試時我應該…
管理做題時間:合理分配作答時間,千萬不要在一個題目上卡太久。
展示計算過程:(針對 FRQ) 清楚解釋每一個步驟,並保留所有過程,避免太多跳躍性思考。
使用正確單位:只要是有單位的物理量,就一定要寫單位!
保持冷靜:穩定步調,遇到難題時不要慌張,如果你覺得很難,那對別人來說也一樣。

範例題
1. A block is released from rest and slides down a track with negligible friction, descending a vertical distance of 5.0 m from its initial position to Point P, as shown in the figure. The block then slides on a horizontal surface where the coefficient of kinetic friction μk between the block and the horizontal surface is 0.20. How far does the block slide on the horizontal surface before coming to rest?
1.0 m
5.0 m
10 m
25 m
2. The velocity as a function of time for an object moving along a straight line is shown in the graph. For which of the following sections of the graph is the acceleration constant and nonzero?
QR only
PQ and TU only
RS and ST only
PQ, RS, ST and TU only
3. The net force F exerted on an object that moves along a straight line is given as a function of time t by \(F(t) = At^2 + B\), where \(A = 1 \, \text{N/s}^2\) and \(B = 1 \, \text{N} \). What is the change in momentum of the object from \(t = 0 \) to \(t = 3 \, \text{s} \)?
6 kg·m/s
12 kg·m/s
17 kg·m/s
30 kg·m/s
4. A spherical star spinning at an initial angular velocity \( \\omega \) suddenly collapses to half of its original radius without any loss of mass. Assume the star has uniform density before and uniform density after the collapse. What is the angular velocity of the star after the collapse?
TOEFL(Test of English as a Foreign Language)是全球最受信任的學術英語能力測驗之一,由美國 ETS 主辦,全球有超過 150 個國家、11,000 多所大學與機構認可。相比之下,IELTS 偏向英式英語且口音多元,SAT 則是學科測驗,僅英文部分與語言能力相關。若你需要證明自己的英文能力,那麼 TOEFL 就是最具代表性的選擇。
