Module 42 - Force and Energy: Problem 2

The Einsteinian and Newtonian expressions for kinetic energy yield nearly the same answers at low velocities and differ at higher velocities. In this problem, you will examine the differences in a couple of examples.

  1. 1. Question

    At what velocity will an object's relativistic kinetic energy be twice as large as Newtonian physics would predict?

    • 1.
    • 2.
    • 3.
    • 4.
    • 5.
  2. 2. Question

    At what velocity will an object's relativistic kinetic energy be ten times as large as Newtonian physics would predict?

    • 1.
    • 2.
    • 3.
    • 4.
