Free Crash Course Physics Lesson: Motion in a Straight Line
If you want to test a Crash Course Physics video lesson before assigning a larger resource set, start with Motion in a Straight Line Crash Course Physics #1. It is the cleanest entry point because students meet the basic language of position, velocity, acceleration, and motion before the series moves into derivatives, integrals, forces, and energy.

Motion in a Straight Line Crash Course Physics #1 YouTube Video Lesson is the free sample lesson for the Physics collection.
Why start with motion in one dimension?
Motion in a straight line gives students a manageable first model: describe where something is, how its position changes, and how quickly that change happens. Before students tackle two-dimensional vectors or Newton’s laws, they need a precise way to talk about motion.
That language also supports later lessons. Derivatives and integrals become more meaningful when students have already seen why physics cares about position, velocity, acceleration, and time.
What teachers are searching for
- A free Crash Course Physics worksheet
- A high school physics video lesson for motion
- A short sub-plan or bell-ringer science lesson
- A Google Classroom-ready physics activity
- A way to preview the full Crash Course Physics lesson set
One-day lesson plan
- Before viewing: Ask students to describe the difference between speed and velocity using a real-world example.
- During viewing: Students complete the time-stamped questions and mark any equation or term they need to revisit.
- After viewing: Students answer one challenge question explaining how position, velocity, and acceleration are connected.
- Assessment: Use the 10-question multiple choice quiz as an exit ticket.
Two-day extension
On Day 2, pair the video guide with a simple graphing or motion example. Students can describe a moving object in words, sketch a position-time graph, and explain how the slope connects to velocity.
Differentiation ideas
- Let students answer the multiple choice quiz instead of all written questions when writing stamina is limited.
- Use vocabulary terms as a pre-teach station before the video.
- Have advanced students rewrite one answer using a formula, graph, or diagram.
Where to go next
After the free lesson, the natural next step is Episodes #2 through #16 Crash Course Physics YouTube Lesson Set, which continues through derivatives, integrals, vectors, Newton’s laws, friction, circular motion, gravity, work, energy, collisions, rotation, torque, statics, fluids, and simple harmonic motion.

Research note
Why this structure works: the NGSS describes science learning as a three-dimensional blend of practices, core ideas, and crosscutting concepts, while the high school physical science expectations emphasize models, mathematical thinking, data analysis, and explanations. The Common Core science and technical subjects standards also ask students to work with domain vocabulary and translate technical information across words, equations, charts, and visual forms. For video-based instruction, active-viewing research and teacher guidance point toward short, purposeful clips with questions that focus attention instead of passive watching.
