- Kinematics of a particle moving in a straight line
- suvat
- v^2=u^2+2as
- s=((u+v)/2)t
- s=ut+1/2at^2
- v=u+at
- s=vt-1/2at^2
- Other equations
- Trapezium = 1/2(a+b)h
- distance = speed x time
- Gravity = 9.81 ms^-1
- A particle slowing down (deceleration or retardation) has negative a.
- Graphs
- speed-time, gradient is acceleration
- speed-time, area underneath is distance travelled
- Units
- Time (t) = seconds (s)
- displacement (s) = metres (m)
- velocity (v or u) = metres per second (ms^-1)
- acceleration (a) = metres per second per second (ms^-2)
