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

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 ...

Distance-time graphs show distance on the vertical axis and time on the horizontal axis. The gradient of a distance-time graph represents speed because gradient = \( \frac{\text{change in y} ...

The latest sensors allow high-resolution (pm) measurements over macroscopic ranges (mm). This category of sensors focuses on metrology applications for the measurement of both absolute distance and ...
