$\text{slope m}=\frac{(\mathrm{y2}-\mathrm{y1})}{(\mathrm{x2}-\mathrm{x1})}$
$\rho =\frac{m}{V}$
mass m = (density ρ)*(Volume)
$ѵ=\frac{\Delta d}{\Delta t}$
distance d = (velocity ѵ)*(t)
$a=\frac{\Delta ѵ}{\Delta t}$
velocity ѵ = (acceleration a)*(t)
distance d = ½acceleration a)*(time t)²
distance d = ½acceleration of gravity g)*(time t)²
momentum p = (mass m)*(velocity ѵ)
gravitational potential energy = (mass m)*(acceleration of gravity g)*(height)
Kinetic energy = ½(mass m)*(velocity ѵ)²
$F=\frac{\Delta p}{\Delta t}$
Force F = (mass m)*(acceleration a)
Force F = −kx
period τ = 1 ÷ (frequency f)
velocity ѵ = wavelength λ * frequency f
Voltage V = current i * Resistance R
Power P = current i * Voltage V
