On the graph of velocity vs. time, Δv/Δt is the slope of the curve. If the curve is straight, the acceleration is constant. If the curve isn't straight we have to do the same trick we did before with ...

Velocity-time graphs show how the velocity (or speed) of a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, decelerating ...

Velocity-time graphs show velocity on the vertical axis ... Between 4 and 7 seconds: the object is travelling at a constant velocity of 8 m/s. It travels \(3 \times 8 = 24~m\).

time and another graph for position vs. time for this same trip ... graph should be continuous - that would make the middle velocity constant (zero slope) and non-zero (so that it matches up ...
