## Resource summary

b) Movement and position
1. How to plot a distance time graph
1. Time always along the bottom (t)
1. Displacement up the side (m/km) (d)
1. Distance/time=V
2. Average speed = Distance moved/Tiem taken
1. Experiment to investigate the motion of everyday objects
1. Examples: Ball rolling down tilted board. Test for how far it rolled in how many seconds.
1. Do twice and find a mean
2. Acceleration = Change in velocity/Time taken
1. a = (v - u)/t
1. change in velocity = final velocity - original velocity
2. How to plot velocity time graphs
1. Time is always along the bottom (t)
1. Speed up the side (m/s) (v)
1. Example (vertical axis) 20m/s & (horizontal axis) 5 seconds. SO acceleration = 20/5 = 4m/s2 (don't forget the squared)
2. AREA = DISTANCE TRAVELLED
1. v * t = d
3. Units - kg, m, m/s, m/s2, N,s, N/kg, kgm/s
