very woo!
PS:
im needing help with my physics homework.....how do you work out acceleration on a speed/time graph? (with a straight line)

I've heard there's a space hopper in these pics somewhere...

its the gradient of the graph.....gah, i can't believe i remember that

speed x time = distance.
here sums upthe entirety of my physics knowledge.

Is the derivative, young grasshopper. Or the average slope between two points, for you non-calculus folk.

it starts at 0m/s and goes to 15m/s in 20 with a steady acceleration. how do i work it out?

v=u+at
so a=(v-u)/t
final velocity- start velocity over time

If it's a straight line, all you need is the slope of that line. Rise over run. (y2-y1)/(x2-x1)=m=acceleration

work out the acceleration for each time segment and find the average of all those results?
