4.) Describe the motion

Motion, in physics, change with time of the position or orientation of a body. Motion along a line or a curve is called translation. ... In both cases all points in the body have the same velocity (directed speed) and the same acceleration (time rate of change of velocity).

In physics, motion is the phenomenon in which an object changes its position over time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time. ... One can also speak of motion of images, shapes, and boundaries.
