... and displacement. Distance is a scalar quantity because it only states the distance travelled (e.g. 1.5km) whereas displacement is a direct line which connects from the start point of an objects, measuring the change of position of a moving body. Displacement is a vector quantity which states the length and direction (e.g. 500m north). Similarly to distance and displacement, speed and velocity are often used ... it a vector quantity. Speed is a measure of how quickly something moves, and can be categorised into instantaneous speed, and average speed. Averaged speed is more commonly use...

... we did in order to investigate the enigma known as the Coulomb balance. We began by using the apparatus shown in Figure 1. This coulomb balance consisted of a torsion balance made of fiber (A), a counter weight, damning vane, and a rod. The sphere b, when charged, would exert a force on sphere a, causing it to spin ... checked one more time by sliding sphere b into position where it barely touched sphere a, and the reading on the scale was 3.8 (the diameter of the spheres), meaning that in fact we had set the apparatus correctly. Following this joyous finding, we then charged the spheres...
