A journey describes the motion of an object over time. A journey can be represented using a distance-time graph. The graph will show when an object is moving and when it is stationary. The graph can ...

Researchers at the University of Missouri have developed a prototype app that combines a smartphone’s GPS, compass and imaging capabilities to calculate the exact location of distant objects and track ...

Researchers found that people make much more accurate estimates when they have access to information about both the speed of a moving object and the timing of its rhythmic patterns. Catching a ...

The brain uses similar computations to calculate the direction and speed of objects in motion whether they are perceived visually or through the sense of touch, scientists report. The brain uses ...

The hyperdrive from Star Wars appears to depict an ultra-relativistic motion through space, extremely close to the speed of light. Under the laws of relativity, you neither reach nor exceed the speed ...

Chris Impey receives funding from the National Science Foundation and the Hearst Foundation. Curious Kids is a series for children of all ages. If you have a question you’d like an expert to answer, ...

An experiment has visualized a prediction about objects traveling at the speed of light known as the Terrell-Penrose effect, ...
