Calculators

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

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

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

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

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 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.

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

Calculates the kinetic energy of an object moving at relativistic speeds, considering the effects of special relativity.

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