Density
D=m/v
Mass
m = dv
Volume
v = m/d
Speed
s = d/t
Time
t = d/s
Distance
d = st
Find Pressure
when you have area and force
P = F/A
pressure = force/area
Find Force
when you have pressure and area
F = PA
Find force
when you have acceleration and mass
F = MA
Find Area
when you have pressure and force
A = F/P
Law of motion
Net force =?
F=MA
force = mass x acceleration
Volume of a Cuboid
V of a cuboid = lwh
Volume = length x width x height
Volume of a Cylinder
Volume of Cylinder = π r^2 h
Where a is constant acceleration, u is initial velocity, v is final velocity, s is displacement from the position when t=0 and t is time taken:
v=?
Where a is constant acceleration, u is initial velocity, v is final velocity, s is displacement from the position when t=0 and t is time taken:
v=u+at
When to use Pythagoras Theorem?
Use pythagoras theorem to find the hypotenuse (longest) side of a right angled triangle when the longest side is opposite the right angle.
a^2 + b^2 = c^2
