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 \(3 \times 8 = 24~m\).

Suppose a car travels only in the x-direction ... to the area under the velocity-time graph. OK, so what if the velocity is changing? What about the case of a constant acceleration?

Precision of the line-width measurement equals axis velocity assumed to be constant multiplied by time. Constant velocity, in this context, is the difference between actual velocity deviation and ...
