Velocity and Distance-Time Graphs

HideShow resource information
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)

Calculating speed from the graphs
Speed = Gradient = Verticle/Horizontal (eg. 500/30) = 16.7 m/s
