Reading formulas
- Each letter stands for a measured quantity. Read a formula as a sentence: d = vt reads “distance equals velocity times time.”
- Letters side by side mean multiply: ma = m × a and PV = P × V. The × is left out so it is not confused with x.
- A constant has the same value in every problem and comes from a reference sheet, such as g = 9.8 m/s² and R in PV = nRT.
- Subscripts are name tags: i is initial and f is final. vi is the initial velocity, not v × i.
- Δ means “change in,” and it is always final minus initial: Δv = vf − vi. A negative Δ means the quantity decreased.
- Case matters: m is mass (g) and M is molar mass (g/mol); v is velocity (m/s) and V is volume (mL).
Formulas in this practice: d = vt, F = ma, W = mg, D = m/V, vf = vi + at, PV = nRT.
