Calculators

Analyzes forces and distances in a lever system based on the fulcrum position.

Calculates the component values (e.g., in L-networks) needed to match impedances for maximum power transfer.

Calculates the change in angular position of a rotating object.

Calculates the output voltage from a simple circuit that divides a source voltage across two resistors.

Calculates the horizontal angle (azimuth) of a celestial body or a point relative to a reference direction (e.g., North).

Estimates how long a battery will last based on its capacity and the device's power consumption.

Calculates the Reynolds number, a dimensionless quantity that helps predict fluid flow patterns (laminar vs. turbulent).

Calculates the spatial period of a wave (distance over which the shape repeats) based on speed and frequency (λ = v/f).

Calculates electrical power using voltage, current, and resistance, based on the formulas P=VI, P=I²R, and P=V²/R.

Calculates the rotational equivalent of linear momentum using the formula L = Iω or L = r x p, where L is angular momentum, I is the moment of inertia, ω is the angular velocity, r is the radius, and p is the linear momentum.
