IB HL Physics Time Dilation
/The new HL Physics course includes special relativity for all students. Below is a tutorial sheet on time dilation.
- Do moving clocks run slower?
- Define proper time.
- A particle has a lifetime of 2.0 µs in its rest frame. The particle moves at 0.8c relative to a laboratory. Find the lifetime of the particle according to an observer in the laboratory reference frame.
- Two detectors in a laboratory are 20.0 cm apart. A particle moving at a constant speed of 0.9 c relative to the laboratory passes through the detectors. What is the time of passge between the detectors as measured in the reference frame of the particle?
