In this energy and mass worksheet, students read about Einstein's formula, E=mc2 and they solve six problems. They convert from different energy units to different mass units using a given formula.

Students solve problems of dilation and velocity. In this geometry instructional activity, students apply the Pythagorean Theorem to solve problems and relate it to time and velocity.

In this elementary particle mass worksheet, learners calculate the mass of elementary particles in kilograms and million electron Volts. Students solve 4 problems finding Top Quark mass, total quark mass of a proton and Strange Quark mass.

Addressed with questions about relative speed and the speed of light, students begin to "think like Einstein" while exploring the science behind the mystery of time travel.
