物理是IB課程中比較有挑戰(zhàn)的一個(gè)科目，想在考試中得到滿意的分?jǐn)?shù)，在考前就需要多練習(xí)真題。首先，練題可以讓你熟悉題型和題目設(shè)置，讓你熟悉考試的時(shí)間，進(jìn)而幫你規(guī)劃好正式考試時(shí)的答題時(shí)間安排。其次，所謂熟能生巧，練得多了，在做完后進(jìn)行反思總結(jié)，你的能力自然也可以得到提升。本文主要分享IB物理SL的考試題和答案，需要的同學(xué)看過來!

一、考試構(gòu)成

1.paper1

一卷主要考選擇題，時(shí)間45分鐘，分?jǐn)?shù)30分，不能用計(jì)算器作答。

2.paper2

二卷可以用計(jì)算器，答題時(shí)間為75分鐘，分?jǐn)?shù)50分。

3.paper3

三卷也可以用計(jì)算器，一個(gè)小時(shí)的答題時(shí)間，分?jǐn)?shù)35分。

二、考試內(nèi)容

三張?jiān)嚲淼目荚噧?nèi)容共涵蓋了物理課程的大部分內(nèi)容，一卷和其余兩張?jiān)嚲眍}型不太一樣，因?yàn)橛羞x擇題。擅長哪張卷的考試內(nèi)容，取決于你前期針對(duì)具體題型練習(xí)了多少真題。

三、IB物理考試題和答案

一卷：

eg.1.A cube has sides of length 10(±1)mm. What is the percentage uncertainty in the volume of the cube?

A. 1%

B. 3%

C. 10%

D. 30%

正確答案選D。

eg.2.In simple harmonic motion,the velocity leads the displacement by a phase angle p. What is the

value of o?

A.Zero

B/4

C.π/2

D.π

正確答案選C。

eg.3.Some of the properties that can be demonstrated using waves are

I. refraction

II. polarization

III. diffraction.

Which properties can be demonstrated using sound waves?

A. I and II only

B. I and III only

C. II only

D. ⅢI only

正確答案選B。

eg.4.A single,narrow slit is illuminated by a parallel beam of monochromatic light and the image is projected onto a screen. Which graph shows how the intensity I of the diffracted light varies horizontally across the screen?

正確答案選B。

二卷：

eg.1.In the drop tower shown,containers with experiments inside of them are fired upwards inside a vertical tower.

The container moves under the influence of gravity and eventually falls back to the bottom

of the tower. Most of the air is removed from the tower so that air resistance is negligible.

While in flight,the container and its contents are in free-fall.

(a)The container is fired vertically upwards with initial speed 48ms-'. Determine the time

that the container is in flight.

(b)At the end of the flight,the container of total mass 480kg falls into a tank of expanded

Styrofoam (polystyrene) spheres to slow it. The container stops after moving a distance

of 8.0m in the Styrofoam.Calculate the average force that acts on the container due to

the spheres.

(c)Outline why the experiments inside the container could be considered to I

be in“weightless”conditions.

正確答案：(a) t=9.8s;(b) F=6.9*104N;(c) 這道題是讓你概述為什么容器內(nèi)的實(shí)驗(yàn)可被視為處于"無重量"狀態(tài)。你可以這樣表述：容器內(nèi)的實(shí)驗(yàn)可以認(rèn)為是失重的，因?yàn)榉醋饔昧κ?，物體和容器將以相同的速度下落!

三卷：

eg.1.A student uses an electronic timer in an attempt to estimate the acceleration of free-fall g.

She measures the time t taken for a small metal ball to fall through a height h of 0.50m.

The percentage uncertainty in the measurement of time is 0.3 % and the percentage uncertainty

height is 0.6%.

(a)Using h=-gt’,calculate the expected percentage uncertainty in the value of g.

(b)State and explain how the student could obtain a more reliable value for g.

正確答案：(a) 1.2%;(b)這是讓你說明并解釋如何才能獲得更可靠的g值。你可以這樣表述：學(xué)生可以用一個(gè)更小的球來獲得更可靠的g值，這樣可以減少空氣阻力。他們也可以使用更大的高度，更頻繁地重復(fù)這一過程，以獲得更可靠的結(jié)果。

以上是IB物理SL考試題和答案以及考試結(jié)構(gòu)完整分享，對(duì)考試備考有疑問，歡迎同學(xué)們找留求藝的專業(yè)老師輔導(dǎo)!
