Electron Speed Calculator Classical vs. Relativistic Speeds from Kinetic Energy Introduction This calculator determines the speed of an electron given its kinetic energy (KE). It provides results from two perspectives:

Work Calculator W = Fd cos(θ) Solve for Work (W) Solve for Force (F) Solve for Distance (d) Work (W) Joules (J) Kilojoules (kJ) Force (F) Newtons (N) Pound-force (lbf)

Relativistic Kinetic Energy Calculator Understanding Relativistic Kinetic Energy Classical physics, described by Newton's laws, provides a formula for kinetic energy (KE = 0.5mv2) that works well for objects moving at

Average Velocity Calculator v = (vi + vf) / 2 Solve for Average Velocity (v) Solve for Initial Velocity (vi) Solve for Final Velocity (vf) Average Velocity (v) m/s km/h
