Calculate wavelength, frequency or wave speed with λ = v/f. Works for light and sound, with wave-type presets, unit conversions and an EM spectrum view.

Calculate the period, frequency, and length of a simple pendulum. Supports eight planets with a live animated visualization.

Find the height, fall time, and impact velocity of a free-falling object under gravity on Earth or any other planet.

Calculate density, mass, or volume with the formula ρ = m/V. Mix units freely, get real-time results, and compare against common materials.

Calculate acceleration, velocity, displacement, or time using kinematic equations. Solve for any variable with step-by-step solutions.

Calculate kinetic energy, mass, or velocity using KE = ½mv². Supports multiple units with real-time results and energy comparisons.

Solve Newton's Second Law (F = ma) for force, mass, or acceleration. Enter any two values to get the third, with multiple units and visual comparisons.

Calculate gravitational potential energy, mass, gravity, or height using PE = mgh. Supports multiple units and one-click planet gravity presets.

Calculate power factor, real power, reactive power, apparent power, and phase angle for AC circuits from any two known values.

Solve velocity, distance, or time with v = d/t. Supports many units, updates in real time, and shows unit conversions, speed comparisons, and solution steps.

Calculate range, max height, flight time, and impact velocity for projectile motion. Visualize the trajectory and compare up to 3 launches.

Calculate frequency, duty cycle, period, and component values for 555 timer IC circuits in astable and monostable modes.
