Check carefully whether a graph is a speed-time graph or a distance-time graph. On true speed–time graphs, the speed has only positive values. On velocity–time graphs the velocity can be negative. Image Tachographs are instruments that are put in lorry cabs to check that the lorry h...
Distance and Displacement, Speed and Velocity Examples: 1. A girl walks 210m in two minutes. Calculate her average speed. 2. A cyclist travels at an average speed of 6m/s for 2 hours. Calculate the distance she covers in this time. 3. The maximum speed limit on UK roads is 70 miles...

There are two variables, however, that exist regardless the temperature or type of medium; those are frequency and wavelength. Wavelength is the distance from one compression to the next in a sound wave. The frequency is how many wavelengths pass by is a set amount of time. These two ...
A method for measuring speed involves calculating and measuring speed of an object based on a distance and a time obtained by a method for measuring distance and a method for measuring time, respectively. The time between distance measur... ...
