1.7 determine acceleration from the gradient of a velocity-time graph

CALCULATING ACCELERATION FROM A VT GRAPH:

- We will use the red line on the picture for our calculations.

- To work out the first sections acceleration we need the equation, a = (v-u) / t.
- This tells us that from 0 m/s to 8 m/s there is a change of 8 m/s.
- The time covered in this interval is 4 seconds.
- So we divide 8 m/s by 4 s which gives us 2 m/s².
- Acceleration is measured in m/s².
