Symbol Definition Unit Unit symbol velocity metre per ms-1 second displacement m t time second s If the velocity is measured over the whole journey then it is known as average velocity, with the . symbol Symbol Definition Unit Unit symbol Average velocity metre per ms-1 second total m displacement t time second s Example A remote control toy car goes 6 m due South and then 8 m due East. It takes two minutes to do this journey. a) Find the distance it travelled and its displacement. b) Calculate its average speed and velocity. d = 14 m v = d/t Solution t = 2 minutes = 2 x 60 = 120 s. v = 14/120 First draw a v = ? v = 0.1166 diagram to v = 0.12 ms-1 help. .
