15 calculadoras
- Projectile Motion CalculatorCalculate the range, maximum height, time of flight, and impact speed of a projectile from its launch speed, angle, and height.
- Gravitational Force CalculatorCalculate the gravitational attraction between two masses with Newton's law of universal gravitation, from their masses and the distance between them.
- Kinetic Energy CalculatorCalculate kinetic energy, momentum, mass, or velocity for a moving object — and see why doubling speed quadruples the energy.
- Density CalculatorCalculate density, mass, or volume from the other two, and compare the result against water and common materials to see what would float.
- Wavelength & Frequency CalculatorConvert between wavelength, frequency, and photon energy for light and any wave, using the wave equation and Planck's relation.
- Ideal Gas Law CalculatorSolve the ideal gas law PV = nRT for pressure, volume, moles, or temperature, with pressure and volume in the units you actually use.
- Pendulum CalculatorCalculate the period and frequency of a simple pendulum from its length and gravity — or find the length needed for a given period.
- Force Calculator (F = ma)Solve Newton's second law F = ma for force, mass, or acceleration, with the result in newtons, pounds-force, and as a multiple of gravity.
- Resistor Color Code CalculatorDecode a four-band resistor's colour bands into its resistance and tolerance, with the value range it guarantees — no more squinting at the rainbow.
- Torque CalculatorCalculate torque — the turning effect of a force — from the force, lever-arm length, and angle, using τ = r·F·sin θ, in newton-metres and pound-feet.
- Hooke's Law CalculatorSolve Hooke's law F = k·x for the spring force, spring constant, or displacement, and find the elastic potential energy stored in the spring.
- Momentum CalculatorCalculate linear momentum (p = m·v) from mass and velocity, with the kinetic energy — the conserved quantity behind collisions, recoil, and propulsion.
- Voltage Divider CalculatorCalculate the output voltage of a two-resistor voltage divider from the input voltage and resistor values, with the current drawn and power dissipated.
- Free Fall CalculatorCalculate the fall time, distance, and impact velocity of an object dropped from rest under gravity, from either the height or the fall time (ignoring air resistance).
- Capacitor CalculatorCalculate the charge and stored energy of a capacitor from its capacitance and voltage (Q = CV, E = ½CV²), and the time constant with a resistor.
