Difference between Speed and Velocity: Speed and velocity are the most basic concepts from Physics. They form the part of your Physics textbook right from early classes when Physics is introduced as a ...

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.

gradient = \(\frac{change~in~y}{change~in~x}\) = \( \frac{change~in~distance}{change~in~time} \) = \(\frac{change~in~metres}{change~in~seconds} \) = m/s. The gradient ...

Difference between distance and displacement: Humans generally not aware of the difference between distance and displacement and thus use these terms interchangeably. But scientifically, these terms ...

The fastest Olympic sprint was Usain Bolt’s 100 meters at the London Games, averaging more than 23 miles per hour for 9.63 seconds. Marathoners, who run for two hours, top out around half of Bolt’s ...

Quantum entanglement, one of the odder aspects of quantum theory, links the properties of particles even when they are separated by large distances. When a property of one of a pair of entangled ...
