Drive the car

Set a speed and watch the position graph draw itself.

time t0s

position x0m

velocity v3m/s

Velocity (works while driving!)3 m/sShow 1-second snapshots

The math, with your numbers

\text{average } v = \frac{\Delta x}{\Delta t} = \frac{0\ \text{m} - 0\ \text{m}}{0\ \text{s} - 0\ \text{s}} = ?\ \text{m/s}

If you never touched the slider while driving, the average equals the speed you set. Change speed mid-drive and see what happens.

Try this

→Drive at +3 m/s. Is the position graph a straight line or a curve?
→Try a negative velocity. Which way does the car go? What happens to the graph's slope?
→Change the velocity while driving. Watch the slope of the position graph change at that moment.

Want to know why it behaves like this?

The lesson “Position & Velocity” explains it step by step: What does 'speed' actually measure?
