Physics Formulas & How to Calculate
View All Math Formulas Handbook →Kinematics & Speed
$$ v = \frac{d}{t}, \quad a = \frac{v - v_0}{t} $$
Velocity is distance divided by time elapsed.
Newton's 2nd Law
$$ F = m \times a $$
Net force equals mass times acceleration.
Work & Energy
$$ W = F \times d, \quad E_k = \frac{1}{2} m v^2 $$
Work is force times displacement; kinetic energy is half mass times speed squared.
Ohm's Law
$$ V = I \times R, \quad P = V \times I = I^2 R $$
Voltage is electric current times resistance.
Potential Energy
$$ E_p = m \times g \times h $$
Gravitational potential energy with $g \approx 9.80665 \text{ m/s}^2$.
Density & Pressure
$$ \rho = \frac{m}{V}, \quad P = \frac{F}{A} $$
Mass per unit volume, and force distributed per unit area.
