Caption: Physics experiment. Screen display of the output from a physics experiment. The experiment involves monitoring changing position with time. The graph shows the position of an object (given as distance in metres) plotted against time (in seconds). The output is a wave of decreasing amplitude. Motion of this sort is seen in a damped oscillator, such as a mass bouncing on a spring, or the swinging of a pendulum. The gradient of the graph shows the velocity of the object. The velocity is zero at the peaks (the high points of a swinging pendulum) and at a maximum in between (the low point of the swing of a pendulum).
