Researchers in Spain reviewed six models used to calculate incidence angle modifier (IAM) losses in photovoltaic systems. They identified the Martín-Ruiz model as the most comprehensive, as it ...

Harvard astronomer Avi Loeb says interstellar object 3I/ATLAS could be firing its "thrusters" to leave the solar system.

Roundabouts are designed for speeds of 15 to 25 mph, so the slower driver is doing the right thing by the law.

F1 is, by far, the most intensive sports environment in the world. Each car is outfitted with more than 300 sensors and generates more than 1 million data points per second during a race. The 10 race ...

Just two drivers were caught speeding after nearly 50 cars were checked along a Leicestershire road. Reports had suggested many were breaking the 40mph limit on the road, but checks show that these ...

Speed is a measure of how fast an object is moving. Calculate speed using the speed equation - speed = distance divided by time. The speed equation can be rearranged to find distance travelled and ...
