Basic Formulas

Force
F = m × a

Force equals mass multiplied by acceleration.

Speed
v = d / t

Speed equals distance divided by time.

Density
ρ = m / V

Density equals mass divided by volume.

Work
W = F × d

Work is done when a force moves an object through a distance.

Power
P = W / t

Power is the rate at which work is done.

Ohm's Law
V = I × R

Voltage equals current multiplied by resistance.
