    mass m = density ρ × Volume V ❖ $\rho =\frac{m}{V}$
    $ѵ=\frac{\Delta d}{\Delta t}$ ❖ distance d = velocity ѵ × time t
    ѵ = at ❖ ѵ = gt ❖ d = ½at² ❖ d = ½gt² where g is the acceleration of gravity ❖ g = 980 cm/s²
    Gravitational Potential Energy GPE = mgh ❖ Kinetic Energy KE = ½mѵ²
    momentum = mass m × velocity ѵ
    $\mathrm{Force}=\frac{\Delta \mathrm{momentum}}{\Delta \mathrm{time}}$ ❖ Force F = mass m × acceleration a
