Watch the car move — and see its distance–time and velocity–time graphs draw themselves, live!
🏁
🚗
Time
0.0 s
Distance
0 m
Velocity
0 m/s
Acceleration
0 m/s²
Distance – Time
slope of this line = velocity
Velocity – Time
area under it = distance · slope = acceleration
🧠 The Big Idea
Uniform speed → distance–time graph is a straight slanted line; velocity–time is flat.
Speeding up (acceleration) → distance–time curves upward; velocity–time slants up.
The steeper the distance–time line, the faster the car is going.
Equations of motion: v = u + at · s = ut + ½at² · v² = u² + 2as
🎯 Try this: Run “Uniform speed”, then “Speeding up”. Notice how the green graph goes from a straight line to a curve — that curve is the sign of acceleration! Then check: is the orange (velocity) graph flat or slanted?
