Distance-Time Graph Explorer
Watch an object move under four different motion types while its distance-time graph draws itself live. Reveal the gradient triangle to see exactly how the slope gives you the speed.

Current speed (gradient)
0.00 m/s
A straight line with steady slope: equal distances covered in equal times.
v = Δs / Δt
speed = gradient of the distance-time graph
What Each Variable Means
s
Distance
How far the object has travelled, in metres (m).
t
Time
How long the object has been moving, in seconds (s).
v
Speed
The gradient of the distance-time graph: v = Δs / Δt, in metres per second (m/s).
