Mass, volume, density — the measurable properties of matter, worked out from first formulas.
Solve for density, mass, or volume using ρ = mass ÷ volume, with the steps shown.
Solve for velocity, distance, or time using v = d ÷ t, with the steps shown.
Find acceleration from the change in velocity over time using a = Δv ÷ t.
Solve for force, mass, or acceleration using Newton’s second law, F = m · a.
Find kinetic energy from mass and velocity using KE = ½ · m · v².
Solve V = I · R for voltage, current, or resistance, with power included.
