Motion & Forces Games — Predict, Watch, Understand
These free motion games let a child predict how things move, watch it happen, and see why. Motion is full of ideas that trip up intuition — why a turning car is accelerating, why a whirled ball flies off straight, why a falling skydiver stops speeding up — so guessing first, then watching, is how it makes sense. No ads, no sign-up.
Predict which is faster — speed is how fast; velocity adds which way it’s going.
Predict the change — speeding up, slowing down or turning all count as acceleration.
Predict the hit — heavier or faster things carry more momentum and are harder to stop.
Predict the push back — every push has an equal, opposite push in return.
Predict the pull — a thing moving in a circle is pulled to the center; let go and it flies straight.
Predict the top speed — a falling thing stops speeding up when air resistance balances gravity.
What kids learn
Motion follows clear rules. Speed and velocity describe how fast and which way; acceleration is any change in that motion. Heavy or fast things carry momentum that is hard to stop, every push has an equal reaction, things moving in a circle are pulled toward the center, and a falling object reaches a steady terminal velocity when air resistance balances gravity. Each game isolates one of these ideas.

Common questions
What is the difference between speed and velocity?
Speed tells you how fast something is going — like 10 metres per second. Velocity tells you how fast AND in which direction — like 10 metres per second heading north. Two cars can have the same speed but different velocities if they are driving in different directions.
What is acceleration?
Acceleration is any change in motion: speeding up, slowing down, or changing direction. A car pulling away from a stop is accelerating; a car braking is accelerating (slowing down); a car turning a corner at steady speed is still accelerating because its direction changes. Only moving in a straight line at constant speed is NOT accelerating.
What is momentum?
Momentum is how much motion something has — it depends on both mass and speed, so a heavy or fast object has a lot of it. The more momentum something has, the harder it is to stop, and the bigger the push it delivers in a collision. A slow truck and a fast bike can have similar momentum.
What age are these motion games for?
Roughly ages 7–13 (grades 2–8), and each game shows its grade band. Speed and velocity suits grades 2–5; acceleration, action-reaction and terminal velocity reach grades 4–7; momentum and circular motion are grades 5–8. The predict-and-watch format needs no reading-heavy setup.
