Motion L15

OUTCOME

By the end of the lesson you will be able to describe and apply the effects of special relativity on energy and thus mass.

As an objects energy increases to close that of light its mass relativistic mass increases.This relationship between mass and energy is expressed in the equation

E = mc2

Effects of relativity

LEARNING TASKS

Explain

Use the equation m = γ mo to show that as the speed of light an object's mass becomes infinite

Explore and Elaborate

Calculate the kinetic energy of an electron that has been accelerated over a potential of 22 GeV

mass of an electron = 9.10938356 x 10-31

Is this value possible?
