Movimento, energia e eletrônica

• Kinetic Energy CalculatorCalculate kinetic energy (KE = ½mv²) for any mass and velocity, with joules and foot-pounds output.
• Ohm's Law CalculatorSolve Ohm's law for voltage, current, resistance or power — enter any two known values.
• Free Fall CalculatorTime to fall, impact velocity, and energy from a drop height — with air-resistance-free and drag-adjusted views.
• Projectile Motion CalculatorRange, max height, and flight time of a projectile from launch speed and angle — no air resistance.
• Force Calculator (F = ma)Newton's second law: solve force from mass and acceleration, with weight and g-force conversions.
• Weight on Other Planets CalculatorSee what you would weigh on the Moon, Mars, Jupiter, and beyond — surface gravity comparison for any mass.
• Wavelength CalculatorFind wavelength, frequency, or wave speed with the wave equation λ = v / f — works for light, sound, radio, and water waves.
• Decibel CalculatorAdd sound levels correctly in decibels, convert between dB and ratio, and see how distance attenuates a sound source.
• Torque CalculatorCompute torque from force and lever arm (τ = F × r), and see the mechanical advantage of wrench extension bars.
• Pendulum Period CalculatorCompute the swing period and frequency of a simple pendulum from its length and local gravity — the formula that ran clocks for 300 years.
• Doppler Effect CalculatorCompute observed frequency from source and observer motion — approaching sirens rise, receding ones fall — with the exact and non-relativistic formulas.
