Extra Practice Problems

Lesson 1

Kinematics

In this lesson, we will define scalar and vector quantities in the context of distance vs. displacement and speed vs. velocity. We will also examine motion/time graphs and the consequential velocity and acceleration graphs.

Homework:

Please use class time wisely to complete your homework. By the next lesson, you should:

Read pages 8-21 in your Oxford text and take notes.
Complete practice questions as you go.
Optional: you may wish to watch my lecture on youtube. I've attached a link.

Please upload photo evidence of your notes and practice problem completion. If you have questions about practice problems, please let me know via Google Chat and we can go over them in class.

Lesson 2

Distance-time graphs

In this lesson, we will explore distance-time graphs, the foundation of Newtonian mechanics. You will analyze the video on the right and use Excel to make charts showing the relationship between distance, time, and velocity.

My video on Excel charts will show you exactly how to insert a well-formatted chart with error bars.

Lesson 3

SUVAT and 2-dimensional motion

SUVAT equations are the equations for the motion of an object under constant acceleration. In this lesson, we will derive the SUVAT equations using the extremely useful velocity-time graphs, look over the characteristics of 2-dimensional motion, and then move onto some in-class exercises.

Lesson 4

Air resistance and terminal velocity

In IB Physics we will frequently assume that air resistance is zero when performing calculations, but you should also be able to qualitatively describe the effects of air resistance. Let's see what we can do with Algodoo!

You will need to download and install Algodoo to create the simulation for today's activity.

To what extent does the use of mathematical models in kinematics shape our understanding of motion, and what are the limitations of these models in representing real-world phenomena?
How do our assumptions—such as neglecting air resistance or assuming constant acceleration—affect the reliability and applicability of the knowledge we gain? This is a critical question in physics and in science in general.
