AS Physics A AQA Unit 2 Equations

HideShow resource information

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…
