如大家所知，IA寫作是IB課程非常重要的一部分，然而這座大山常常會(huì)難住很多同學(xué)，其中要邁過(guò)的第一道坎就是選題的問(wèn)題。同學(xué)們不要慌，打擊可以仔細(xì)看看物理課程大綱的學(xué)習(xí)內(nèi)容，根據(jù)大綱思考題目會(huì)順利很多，其次，也可以從熱物理、力學(xué)、波、電和磁等方面入手。今天小編為大家收集了10個(gè)IA選題，可供參考。

1, How does sugar concentration affect the refractive index of water?

糖濃度如何影響水的折射率？

2, How does the number of coils affect the efficiency of an electric motor?

5, Investigate how the radius of a football affect the impulse on the football when kicked?

調(diào)查足球的半徑如何影響足球被踢時(shí)的沖動(dòng)？

6, Exploring the relationship between angle of initial release of a pendulum and the subsequent calculation of ‘g’ from the pendulum.

探索擺的初始釋放角度與隨后計(jì)算擺的“g”之間的關(guān)系。

7, How does temperature affect the flight distance or arc of an elastic band when fired?

溫度如何影響發(fā)射時(shí)彈性帶的飛行距離或弧度？

8, Set up a hydraulics system and change multiple variables to test the impact.

9, Investigate the impact of different levels of shade on the power output of a solar panel.

調(diào)查不同程度的陰影對(duì)太陽(yáng)能電池板功率輸出的影響。

10, Investigate the impact of various variables (temperature, concentration, colour) of a liquid on its refractive index.

調(diào)查液體的各種變量（溫度、濃度、顏色）對(duì)其折射率的影響。

【微語(yǔ)】你踏上異國(guó)的土地, 追尋夢(mèng)想的翅膀在風(fēng)中展開, 每一步都是成長(zhǎng)的印記。
