Physics Calculators

Physics calculators for mechanics, electricity, and optics. Explore our collection of 6 accurate, real-time calculators below.

Solve for speed, distance, or travel time with automatic conversions and a comparative velocity scale.

Calculate Voltage, Current, Resistance, or Power based on Ohm's Law with an interactive electrical triangle diagram.

Calculate Force, Mass, or Acceleration (F = ma) with a dynamic vector arrow and pushing crate physical diagram.

Calculate Average Velocity, Displacement, or Time (v = d / t) with real-world benchmark velocity comparisons.

Calculate Acceleration, Initial/Final Velocity, or Time (a = delta v / t) with a dynamic velocity-time slope line plot.

Calculate Kinetic Energy, Mass, or Velocity (KE = 0.5 * m * v^2) with a live rolling ball physics simulation track.
