Photoelectric Effect Calculator
Calculates the kinetic energy of electrons ejected from a material when light shines on it, based on photon energy and work function.
Centripetal Force Calculator
Calculates the centripetal force required to keep an object moving in a circular path.
dBm to Watts Calculator
Converts power levels between decibels relative to one milliwatt (dBm) and watts. dBm is a logarithmic unit, and this calculator helps convert it to the linear unit of watts.
Work Calculator
Calculates the work done by a force acting over a distance. Work is calculated using the formula: W = Fd cos θ, where W is work, F is force, d is distance, and θ is the angle between the force and the direction of motion.
