Velocity and Distance-Time Graphs 0.0 / 5 ? PhysicsEnergyGCSEAQA Created by: Em_AllTimeLowCreated on: 14-04-16 14:04 Speed Speed is only how fast you are going, without taking into account the direction. 1 of 11 Velocity Velocity is the same as speed, but mush also have the direction specified. E.g. 30mph North 2 of 11 Very important notes for Distance-Time graphs No1 Gradient = speed 3 of 11 Very important notes for Distance-Time graphs No2 Flat sections are where its stationary - Its not moving 4 of 11 Very important notes for Distance-Time graphs No3 Straight uphill or downhill sections means it is travelling at a steady speed 5 of 11 Very important notes for Distance-Time graphs No4 The steeper the graph, the faster it is going 6 of 11 Very important notes for Distance-Time graphs No5 Downhill sections mean its going back to its starting point 7 of 11 Very important notes for Distance-Time graphs No6 Curves represent acceleration or deceration 8 of 11 Very important notes for Distance-Time graphs No7 A steepening curve means its speeding up (Increasing gradient) 9 of 11 Very important notes for Distance-Time graphs No8 A levelling off curve means its slowing down (Decelerating gradient) 10 of 11 Calculating speed from the graphs Speed = Gradient = Verticle/Horizontal (eg. 500/30) = 16.7 m/s 11 of 11
