Lesson 1-2

Forces

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

Topic A.2 - Forces

Lesson 3

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.

Momentum and Impulse

In Lesson 4, we will take a look at the primary tools used to analyze explosions and collisions: Momentum and Impulse.

Handouts:

Collisions and explosions!

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

Challenge: Build your own cart simulation in algodoo

Topic 2.4 - Momentum and Impulse

Lesson 5

Circular Motion

In this lesson, we will take a look at how we can relate objects traveling circular paths to velocity, time, acceleration, and other fun stuff!

Handouts:

Geogebra simulation of change in velocity.

TOK linKs

To what extent can our understanding of forces and motion be considered objective, given that the interpretation of physical laws depends on human-designed systems and frames of reference?
How are technological advancements (e.g., motion sensors, simulations) extensions of our own senses? As students of knowledge, how can we learn to trust them?
