Physics is feeling the forces

Physics problems are word problems pretending to be math problems. The hard part is not the algebra; it is figuring out what is happening. A ball rolling down a ramp. A car accelerating. A rope swinging. You have to SEE it before you can solve it.

The tools stack

PhET Simulations (phet.colorado.edu): free, play with gravity, circuits, waves
ChatGPT or Claude: draws free-body diagrams using text, explains setups
Wolfram Alpha: computes anything once you have the equations
Photomath: handles many physics word problems
Algodoo: sandbox physics simulator, great for intuition

Free body diagrams, AI-assisted

A free body diagram shows all forces on an object: gravity down, normal force up, friction back, applied force forward. Drawing these is a skill. AI can describe them for you, but YOU should draw them to build intuition.

Good physics prompt: 'A 5 kg box sits on a 30-degree incline. There is friction with coefficient 0.2. Walk me through the free body diagram. Label each force. Do NOT solve the problem yet. I want to draw it myself from your description.'Ask for the setup, not the solution.

PhET: the secret weapon

PhET is free physics simulations from the University of Colorado. You drag sliders and see what happens. Pair it with AI: read the topic, play with the sim, ask AI questions about what you saw. This builds real intuition in minutes.

Textbook-only study	PhET + AI
Read about projectile motion	Actually launch a cannon at different angles
See one diagram	See 1000 trajectories
Ask teacher next class	Ask AI the exact question right now
Memorize formula	See when formula breaks (air resistance)

Where AI struggles with physics

Anything that requires a diagram ChatGPT cannot see
Problems with unusual setups (ramps with springs, etc.)
Getting signs right (positive vs negative directions)
Quantum and relativity problems - often hallucinates

The honest learning path

Read the problem. Draw a picture
Draw the free body diagram yourself
Pick your axes and direction (+x, -y, whatever)
Write equations of motion
Now and only now, use Wolfram to solve the algebra
Check: does the answer make physical sense?
Redo the tricky part on paper to lock it in

If you can't explain it simply, you don't understand it well enough.
— Albert Einstein

The big idea: physics is intuition first, math second. Use PhET and AI to build the intuition. Save the heavy math for when you already see the setup.

What is the main idea of "Physics With AI: Simulations, Vectors, and Free Body Diagrams"?
1. Physics needs intuition. PhET simulations plus AI explanations give you that intuition faster than any textbook.
2. Use AI as the final authority for the whole decision
3. Avoid checking the answer once it sounds polished
4. Focus only on speed instead of judgment
Which concept is most central to "Physics With AI: Simulations, Vectors, and Free Body Diagrams"?
1. simulations
2. physics
3. free body diagrams
4. vectors
Which use of AI fits this topic best?
1. Let the AI decide what matters without your review
2. Use the answer before checking whether it fits the situation
3. PhET Simulations (phet.colorado.edu): free, play with gravity, circuits, waves
4. Use the first answer without checking it
What should a careful learner remember about "Check the signs"?
1. Use AI to draft or organize ideas about physics, then verify before acting.
2. Skip the context so the tool can guess faster
3. Treat the output as private even after sharing it online
4. Use the answer without checking the source
You want to use AI after this lesson. What is the safest next step?
1. Act immediately because the AI answer is written clearly
2. Use the AI answer as a draft, then check it against a reliable source.
3. Hide uncertainty so the final answer looks cleaner
4. Use private or sensitive details before checking permission
How should AI output about physics be treated?
1. As proof that no other source is needed
2. As a replacement for context, consent, or expert review
3. As a draft or helper output that still needs human judgment and verification
4. As something that becomes correct when it sounds confident
Name one way to verify an AI answer about physics.
Which action would help you apply "Physics With AI: Simulations, Vectors, and Free Body Diagrams" responsibly?
1. Use the tool to avoid thinking through the tradeoff
2. Keep going even if the output conflicts with a trusted source
3. Use the first answer without checking it
4. ChatGPT or Claude: draws free-body diagrams using text, explains setups
