Physics

Calculate angular velocity from angle and time, or convert rad/s, deg/s, RPM, and Hz with clear units and signed results.

Calculate centrifugal force in N or lab RCF in x g with clear modes, unit help, and solve-for options.

Convert RPM to RCF or solve RPM from target RCF using rotor radius, unit conversion, and radius position notes.

Calculate rotational kinetic energy from inertia and angular speed, or use common shapes to find inertia first.

Calculate rotational stiffness, torque, or angle using direct, torsion bar, or beam-end spring formulas with clear unit handling.

Calculate SHM values for a spring or small-angle pendulum using amplitude-phase or initial conditions.

Calculate pendulum period, frequency, angular frequency, or length, with a large-angle comparison and validity note.

Calculate torque, force, or lever arm distance with angle handling, unit conversion, and optional signed clockwise/counterclockwise results.

Calculate centripetal force, acceleration, speed, angular speed, and period with clear SI units and beginner-friendly notes.

Calculate wavelength, frequency, wave speed, photon energy, period, and wavenumber for general waves or EM waves.
