Kinematics
Map position, checkpoints, speed stats, bikes, and sprint starts.
Physics for ages 11-14, taught like a game tutorial
Turn game movement into physics.
Start with the stats kids already know from games: map position, distance to a checkpoint, speed, direction, and boosts. Then the quiz math has a place to land.
Game stats become physics words
Boosts change speed: acceleration
Like a game tutorial
Learn the controls before the boss fight.
The lesson builds the basic words first, then the formulas, then the quiz. No mystery symbols before the idea makes sense.
Forces
Boosts, heavy carts, sticky floors, shoes, and phone vibrations.
Energy
Skate ramps, braking, batteries, and work as energy transfer.
Momentum
Seatbelts, rebounds, helmets, and why stopping time matters.
Waves
Noise canceling, music speakers, stadium waves, and light.
Electricity
Circuits through chargers, LEDs, controllers, and motors.
Lesson 1: motion basics
Motion is just changing game stats.
Before any formula, know what each stat means. If a player, kart, or bike moves on a map, physics can describe it.
Game movement translator
Read the HUD before the math.
- Position is the player or bike's spot on the map.
- Distance is how much path was actually traveled.
- Speed is how much distance is covered each second.
- Velocity is speed plus direction.
- Acceleration is how quickly velocity changes because of a boost, brake, or turn.
If a kart moves right at 4 m/s, its velocity is 4 m/s right. If a boost makes that number grow each second, that is acceleration.
Position
Your spot on the map compared with a start point. Spawn can be 0 m. A checkpoint might be 30 m.
Distance
How much path you actually traveled. If you run from spawn to a 30 m checkpoint, distance is 30 m.
Time
How long the move took on the clock. If the level timer says 6 seconds, time is 6 s.
Speed
How much distance you cover each second. The quiz formula is speed = distance / time.
Velocity
Speed with a direction. 5 m/s right and 5 m/s left are different velocities.
Acceleration
How quickly velocity changes. A kart going from 2 m/s to 5 m/s is accelerating.
Direction matters
A boost with your motion speeds you up. A brake or wall bump against your motion slows you down.
Think first
Game movement warm-up
Imagine a racing game level. You are not solving yet. You are learning which stat the question is asking for.
- Where did the player spawn? That starting spot is position 0 m.
- How far is the checkpoint? That path length is distance.
- How many seconds are on the level clock? That is time.
- How many meters happen each second? That is speed.
- Which way is the player moving? Speed plus direction is velocity.
- Did a boost, brake, or turn change velocity? That change is acceleration.
Game movement translator
Turn the story into player stats.
- Spawn point
- position at the start
- Checkpoint gap
- distance traveled
- Level timer
- time in seconds
- Speed stat
- meters each second
- Boost or brake
- acceleration
Quiz cheat sheet
For the first quiz, follow these checkpoints.
- Find the distance number in the story.
- Find the time number in the story.
- Use speed = distance / time.
- Keep the unit: meters per second means m/s.
Position: 0.0 m
Speed: 0.0 m/s
Velocity: 0.0 m/s right
Acceleration: 0.0 m/s^2
Training level: speed
A bike avatar travels 24 meters in 6 seconds. Use the idea, not a memorized answer: speed tells you how many meters are covered each second.
- Distance = 24 m
- Time = 6 s
- Speed = distance / time
Lesson 2: forces
Now push the cart like a game object.
Push, mass, and friction behave like game stats. Boost force tries to speed up the cart, friction fights it, and mass is how heavy the cart feels.
Force boss fight
Which side wins the push?
Imagine a kart on a sticky floor. A boost force pushes right. Friction pushes left. Net force is the leftover force after the two sides fight.
Quiz cheat sheet
Use these checkpoints for forces.
- net force = boost force - friction
- acceleration = net force / mass
- speed after time = acceleration x time
Acceleration: 0.00 m/s^2
Velocity: 0.00 m/s
Net force: 0.0 N
Quiz practice
Use the game stats, then check your work.
This is the boss fight, but it is split into checkpoints so the quiz feels doable.
Kart Boost Challenge
A 12 kg kart starts from rest. A boost force pushes 42 N to the right. The sticky floor adds 6 N of friction to the left. Find the winning force, then how the speed stat changes.
- Boost force = 42 N right
- Friction = 6 N left
- Mass = 12 kg
- Time = 3 s
Memory practice
Cards come back like daily quests.
Write your answer first. Then reveal it, grade it, and the card comes back sooner when it was tough.
What does net force mean?
For adults
Why this lesson is built this way.
Short videos can help, but they are not enough.
A video can make a topic feel familiar. Students still need to predict, try, calculate, explain, and check their own work.
Doing the work builds the skill.
Physics is not just recognizing a formula. The student has to choose the right idea and use it on a new situation.
Simulations work better with missions.
Dragging sliders is more useful when a learner has a mission: predict, test, explain, calculate, and revisit.
Memory needs repeat visits.
The recall cards ask for an answer first, then show the model answer, then bring the idea back later.
