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, or still.

Tomography enables the reconstruction of objects, and its application to moving objects uncovers otherwise hidden phenomena, particularly at light velocity. Li et al.present a tomographic method ...

Terminal velocity is the maximum speed achieved by an object freely falling through a gas or liquid. At terminal velocity, the forces acting on the object are balanced so it is no longer accelerating.

There has long been a mystery when calculating how an incoming light wave scatters off an object and becomes a modified, ...
