12. Position-time graphs for UALM

The position-time graph in a uniformly accelerated motion is a parabola, that does not necessarily have to start from the origin.


Position (x) is in a quadratic proportion to time (t), and so, we get a curve called parabola when we represent the position-time graph for a uniformly accelerated motion.

Notice that in the graph on the right, the initial position is not = 0. Initial position , xi is 10 m.

The slope of the curve (parabola) is not constant, so, the velocity for this type of movement is not constant, as we already know.
