Lesson 3: Models and Representations
In this lesson, you will begin learning about the use of representations and models in physics.
There are 2 learning objectives for this lesson:
- Use models and representations to visualize complex physical phenomena in a simpler way.
- Calculate the average speed and average velocity of an object.
The Particle Model
The particle model is used as a way to simplify things. Let’s say we want to analyze the motion of a cow. Let’s call our cow Daisy. We want to find out how long it takes Daisy from the fence gate to the barn when she hears the dinner bell.
