average speed= distance/ time
average velocity= displacement/ time
range= largest repeat value- smallest repeat value
uncertainty= (1/2)range
percentage uncertainty= uncertainty/ average x100
acceleration= change in velocity/ change in time
(initial velocity 'u' final velocity 'v' acceleration 'a' time 't' displacement 's')
v = u + at
v^2 = u^2 + 2as
s = ut + (1/2) at^2
s = (1/2) (u + v) t
weight= mass x gravitational field strength
force= mass x acceleration
work= force x displacement
work= force x displacement x cos(angle)
kinetic energy= (1/2) mass x velocity^2
potential energy= mass x gravity…
