Physics

Motion and projectiles, Ohm’s law, energy and work, gravitation, waves and resistors.

• Projectile Motion CalculatorFind the time of flight, range, maximum height and impact speed of a projectile from its launch speed, angle and height, on Earth, the Moon or Mars.
• Constant Acceleration Calculator (SUVAT)Enter three of initial speed, final speed, acceleration, time and displacement and get the other two from the equations of motion.
• Ohm’s Law and Power CalculatorEnter any two of voltage, current, resistance and power and get the other two with Ohm’s law and the power law.
• Kinetic and Potential Energy CalculatorCalculate kinetic energy, gravitational potential energy, total energy, momentum and the landing speed from mass, speed and height.
• Work and Power CalculatorCalculate the work done by a force over a distance at an angle, and the average power when the time is known, in joules, watts and horsepower.
• Universal Gravitation CalculatorCalculate the gravitational pull between two masses with Newton’s law, plus the gravitational acceleration, circular orbital speed and escape speed from a planet.
• Wave Calculator: Frequency and WavelengthConvert between frequency, wavelength and period for a sound wave, light or any medium, with the photon energy of light.
• Series and Parallel Resistor CalculatorEnter resistor values and get the equivalent resistance in series or parallel, with the total current and power when the voltage is known.
