Newton’s Grand Prix

Race down the track, dodge traffic and oil, and grab coins. At every pit stop you revise part of the chapter and answer three questions; each right answer is a nitro boost for the next lap.

How to play

Race down the track, dodge traffic and oil, and grab coins. At every pit stop you revise part of the chapter and answer three questions; each right answer is a nitro boost for the next lap.

On a computer: Left and right arrow keys to steer, Space for nitro
On a phone: Hold ◀ ▶ or drag on the track to steer; tap Nitro to boost

What you’ll revise

Class 9 Science: Motion, Force and Laws of Motion

Lap 1 · Speed and velocity
- Speed = distance ÷ time. Its SI unit is metres per second (m/s).
- Velocity is speed in a given direction, so it is a vector quantity.
- Displacement is the shortest distance from start to finish, and it can be zero.
Lap 2 · Acceleration
- Acceleration = change in velocity ÷ time taken, measured in m/s².
- The equations of motion include v = u + at and s = ut + ½at².
- Slowing down is negative acceleration, also called retardation.
Lap 3 · Newton’s laws
- First law: an object keeps still or keeps moving unless a force acts on it. This tendency is inertia.
- Second law: force = mass × acceleration (F = ma). 1 N = 1 kg × 1 m/s².
- Third law: every action has an equal and opposite reaction, acting on a different object.

Students build games like this. In the Beginner cohort, each student turns a chapter of their own syllabus into a game, then revises with it for 10 minutes a day.
