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.
