Summarise your notes
Learn your notes
Check the revision PowerPoint
Test your learning by attempting worksheets and past paper questions – you should spend the same amount
of time on questions as note making
The revision PowerPoints can be accessed on the school website. They contain summary notes, worked examples,
past paper questions and solutions. To open each PowerPoint, click the read only option.
In addition to the PowerPoints, you will also receive a folder of past papers. It is essential that you test your learning
by attempting these. The majority of papers included are from the previous specification, but most of the questions
still apply:

Motion
speed = distance/time *
s
vxt
velocity = displacement/time *
s = distance or displacement in m
v = speed or velocity in m/s
t = time in s
speed = gradient of distance-time graph
velocity = gradient of displacement-time graph
acceleration = gradient of velocity-time graph
displacement = area between graph and time
axis of velocity-time graph
F = ma
F
mxa
F = resultant force
m = mass in kg
a = acceleration
(v – u)
a x t
a = (v-u) / t
a = acceleration (or rate of change
of speed) in m/s2
v = final speed or velocity in m/s
u = initial speed or velocity
t = time in s
s = ½(u+v) t
v = u + at
v2 + u2 + 2as
s = displacement in m
u = initial velocity in m/s
v = final velocity in m/s
t = time in s
s = ut + ½at2
momentum = mass x velocity *
M
mxv
Energy
efficiency = useful output energy / total input energy *
GPE = gravitational potential energy in J
m = mass in kg
g = 10 m/s2
h = height in m
WD
Fxd
work done = force x distance *
KE = ½ mv2
WD
P x t
power = work done / time *
GPE = mgh
KE = kinetic energy in J
