About this Simulation

This interactive simulation models the motion of a charged particle in a constant electric force field, revealing how relativistic effects dominate as velocity approaches the speed of light. Learners can adjust the applied force and observe real-time changes in velocity, energy, acceleration, and the Lorentz factor, discovering why Newtonian mechanics fails at extreme speeds.

Learning objectives: Understand how relativistic mass and Lorentz factor affect particle acceleration | Compare classical and relativistic predictions for motion under constant force | Explore the asymptotic behavior of velocity as it approaches the speed of light
