Topic 2.1 - Lesson 1

Time distance 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.

Topic 2.1 - Lesson 2

Motion in two dimensions

Note: you should definitely review vectors!!

In Lesson 2, we consider motion in two dimensions, looking at the vertical and horizontal components of velocity.

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

After completing the simulation activity, we will work on this problem set in class. Printed copies will be provided on request.

Topic 2.2 - Lesson 1

Forces

In our first lesson for Topic 2.2, we'll take a look at forces. Newton's Laws! Free body diagrams! Trigonometry! THE BEST.

Topic 2.2 - Lesson 2

Static Friction

In this lesson, we will revisit a critical free-body diagram from our previous lesson: an object resting on a ramp. This foundational free-body diagram is the key to understanding how gravitational weight is split into the components that cause acceleration down a ramp.

Stuck? Here are some Example Free Body Diagrams.

Topic 2.3 - Lesson 1

Work, Power, and Energy

In Topic 2.3, we focus our energy (get it?) on converting work into gravitational potential, kinetic, and elastic energy.

Topic 2.4 - Lesson 1

Momentum and Impulse

In Topic 2.4, we will take a look at the primary tools used to analyze explosions and collisions: Momentum and Impulse. Make sure that you complete the reading and watch the video!

Topic 2.4 - Momentum and Impulse

Collisions and explosions!

This simulation includes cart simulators for collisions and explosions: SIMULATION!
