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.

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.

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 ...

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