Equations of Motion

From our work on speed-time graphs, it should be obvious to you that the graph below shows something accelerating.
acceleration from u to v m/s in t secondsThe initial velocity is given the letter u.
The final velocity, v.
The time taken for the acceleration is t.

The slope, or gradient, of the line is = (v-u)÷t, which is, of course, the acceleration!
