The position in meters of a car that is accelerating, detected every half second.
The differences between one data and another:
I copy and paste the differences into the first box:
The second differences are constant: the movement has a constant acceleration.
I can copy the data in the "notes" section:
The acceleration (m/s²) is Δs/(Δt)² = 0.75/0.5² = 0.75/0.25 = 3.
• The time that a program takes to multiply two N*N matrices, in the case of different values of N: see the example.
