Unit 1 — Kinematics

<aside> 📘

Goal for Unit 1: know the core definitions, use consistent signs, and choose the right kinematics equation based on what is constant (usually acceleration).

1) Motion diagrams

What is a motion diagram?

• A motion diagram shows an object’s position at equal time intervals using dots.

Key patterns (spacing between dots)

• Equal spacing → constant velocity (no acceleration)
• Dots getting farther apart → speeding up (acceleration)
