$\text{slope m}=\frac{(\mathrm{y2}-\mathrm{y1})}{(\mathrm{x2}-\mathrm{x1})}$
Volume V = length l × width w × height h
mass m = density ρ × Volume V
$\rho =\frac{m}{V}$
distance d = velocity ѵ × time t
$ѵ=\frac{\Delta d}{\Delta t}$
$a=\frac{\Delta ѵ}{\Delta t}$
ѵ = at
d = ½at²
d = ½gt²
where g is the acceleration of gravity.
g = 980 cm/s² (cgs)

Gravitational Potential Energy = mgh
Kinetic Energy = ½mѵ²
momentum p = m ѵ
$\text{Force}=\Delta \text{momentum}$
$\text{Force}=\text{mass}\times \frac{\Delta ѵ}{\Delta t}$
Force = mass × acceleration
$\text{efficiency}=\frac{\text{actual mechanical advantage}}{\text{ideal mechanical advantage}}$
where:
a is acceleration
d is distance
Δ is "the change in" (greek lowercase delta)
m is mass
p is momentum
t is time
ѵ is velocity
period τ = 1 ÷ (frequency f )
velocity ѵ = wavelength λ * frequency f
