what is the equation for pressure? 
$p =$ $f/a$
p = pressure ( N/m)^2
f = force (N)
a = area (m^2)
what is the equation for moment? 
$m =$ $f x d$
m = moment
f = force
d = perpendicular distance to pivot
what is the equation for the force in elasticity? 
$f =$ $kx$
f = force (N)
k = spring constant (N/m)
X = extension (m)
what is the equation for work done? 
$w =$ $f x s$
w = work done (J)
f = force (N)
s = distance travelled in direction of the force
what is the equation for force ( acceleration)? 
$f =$ $ma$
f = force (N)
m = mass (kg)
a = acceleration (m/s)^2
what is the equation for acceleration? 
$a =$ $Δ v/ t$
a = acceleration (m/s)^2
Δ = change in
v = velocity
t = time
what is the equation for wave speed? 
$v =$ $fλ$
v = wave speed (m/s)
f = frequency (Hz)
λ = wavelength (m)
what is the equation for time period? 
$f =$ $1/t$
f = frequency (Hz)
t = time period (s)
