PHYSICS
Physics formulas: units first, formula second
Connect SI units to force, energy, waves, heat, gas and electricity calculations.
Physics formulas are compact because the units carry meaning. Force is mass times acceleration; work is force times displacement; electrical power is voltage times current under the stated assumptions.
