Why kinematics first
Every physics course starts here for a reason.
Kinematics is the language the rest of mechanics is written in. Before forces, before energy, before momentum — you need to be fluent in reading how position, velocity, and acceleration relate on a graph. Get this unit right, and everything after it gets easier.
The unit
Six lessons. One curve at a time.
Each lesson is a point on the path — built for AS/A Level and IB Physics together, where the two overlap almost completely.
Distance & Displacement
Two runners, two totals — only one of them cares which way you're facing.
Start lessonSpeed & Velocity
More than speed — direction matters.
Start lessonAcceleration
Speeding up, slowing down, or turning — all of it counts.
Start lessonThe Equations of Motion (SUVAT)
Five variables, four equations, and you never need all five at once.
Start lessonGraphical Analysis of Motion
Slope, area, and curvature — a graph is three answers in one picture.
Start lessonFree Fall & Projectile Motion
Two directions, completely independent, happening at once.
