Physics Tools
Interactive physics tools for students and educators. Calculate speed, distance or time with v=d/t, compute acceleration and kinematics with equations of motion, find force, mass or acceleration with Newton's second law F=ma, calculate projectile range, max height and flight time, determine free fall time, impact velocity and distance, compute kinetic energy from mass and velocity, calculate gravitational potential energy, find wavelength, frequency or wave speed with dedicated frequency-to-wavelength conversion, compute linear momentum and solve elastic/inelastic collision problems, calculate density, mass or volume, determine static and kinetic friction forces, find pendulum period, frequency and length, convert between decibel levels and sound intensities, and calculate heat transfer with Q=mcΔT.
Convert between decibels and ratios, combine multiple sound sources, and find how sound levels change with distance, with real-time results and hearing-safety warnings.
Solve friction force, coefficient, or normal force from Ff = μ × N. Handles static and kinetic friction with real-time results, a material reference table, and a normal force helper.
Calculate linear momentum (p = mv), solve for mass or velocity, and analyze elastic or perfectly inelastic collisions with unit conversions and energy analysis.
Solve the Q = mcΔT heat equation for heat energy, mass, specific heat, or temperature change, with a 20-material lookup table and unit conversions.
Calculate wavelength, frequency or wave speed with λ = v/f. Works for light and sound, with wave-type presets, unit conversions and an EM spectrum view.
Calculate the period, frequency, and length of a simple pendulum. Supports eight planets with a live animated visualization.
Find the height, fall time, and impact velocity of a free-falling object under gravity on Earth or any other planet.
Calculate density, mass, or volume with the formula ρ = m/V. Mix units freely, get real-time results, and compare against common materials.
Calculate acceleration, velocity, displacement, or time using kinematic equations. Solve for any variable with step-by-step solutions.
Calculate kinetic energy, mass, or velocity using KE = ½mv². Supports multiple units with real-time results and energy comparisons.
Solve Newton's Second Law (F = ma) for force, mass, or acceleration. Enter any two values to get the third, with multiple units and visual comparisons.
Calculate gravitational potential energy, mass, gravity, or height using PE = mgh. Supports multiple units and one-click planet gravity presets.
