Physics Calculators
Physics describes the fundamental laws governing motion, energy, and the forces that shape our universe. Our physics calculators help students solve homework problems, engineers design systems, and anyone curious about the physical world understand the mathematics behind everyday phenomena.
Classical mechanics calculators cover Newton's laws with tools for force, acceleration, momentum, and work calculations. Energy calculators compute kinetic and potential energy for objects in motion or positioned within gravitational fields. These concepts form the foundation of physics education and engineering applications from automotive design to aerospace systems.
Electrical calculators apply Ohm's law and related formulas for circuit analysis, essential for electronics hobbyists and electrical engineers. Wave calculators determine frequency, wavelength, and wave speed relationships important in acoustics, optics, and telecommunications. Thermodynamic tools like the pressure and density calculators support applications in fluid mechanics and material science.
All Physics Calculators
Ohm's Law Calculator
Calculate voltage, current, resistance, and power using Ohm's law (V = IR) and the power equation. Enter any two values to find the others. Essential for circuit design and electrical troubleshooting.
Force Calculator
Calculate force using Newton's second law (F = ma). Enter mass and acceleration to find force in newtons, or solve for mass or acceleration given the other values. Includes unit conversions.
Kinetic Energy Calculator
Calculate the kinetic energy of a moving object using KE = 1/2mv². Enter mass and velocity to find energy in joules. Also calculates velocity or mass given kinetic energy.
Potential Energy Calculator
Calculate gravitational potential energy using PE = mgh. Determine the energy stored in an object based on its mass, height, and gravitational field strength. Supports various unit systems.
Momentum Calculator
Calculate linear momentum using p = mv. Find the momentum of an object given its mass and velocity, or solve for either variable. Includes collision analysis for elastic and inelastic collisions.
Wavelength Calculator
Calculate wavelength, frequency, or wave speed using the wave equation. Supports electromagnetic waves, sound waves, and other wave phenomena. Includes conversions between Hz, kHz, MHz, and GHz.
Acceleration Calculator
Calculate acceleration from velocity change and time (a = Δv/t) or from force and mass (a = F/m). Supports uniform acceleration and includes kinematic equation calculations for motion problems.
Density Calculator
Calculate density, mass, or volume using the density formula (ρ = m/V). Compare calculated densities to common materials and determine if objects will float or sink in various fluids.
Pressure Calculator
Calculate pressure from force and area (P = F/A) or using fluid pressure equations. Convert between pascals, atmospheres, bar, psi, and other pressure units for engineering applications.
Work Calculator
Calculate mechanical work using W = Fd (force times displacement). Accounts for angle between force and motion vectors. Converts between joules, foot-pounds, and other energy units.
