Total Energy

Total Energy Equation 38-40 gives an object’s mass energy (or rest energy) Eo that is associated with the object’s mass m, regardless of whether the object is at rest or moving. If the object is moving, it has additional energy in the form of kinetic energy K. If we  assume that its potential energy is zero, then …

Time Dilation

Time Dilation Suppose now that two events occur at the same place in S’ (so .1x’ = 0) but at different times (so .1(‘ “* 0). Equation 38-22 then reduces to     This confirms time dilation. Because the two events occur at the same place in S’, the time interval t!.(‘ between them can be measured …
