  2. Answer the following warm up question about Einstein’s postulates on your own

  3. Headlights are turned on 3 trains traveling at v1 =.1c,v2 = .5 c, and v3 = .7 c. Rank the speed of the light beams from least to greatest as seen by observer next to the track . (TPS) • 1 < 2 < 3 • 1 > 2 > 3 • 1 < 3 < 2 • 1 > 3 > 2 • The speed is the same for all of the light beams

  4. Consult with your neighbors and answer again

  5. Headlights are turned on 3 trains traveling at v1 =.1c,v2 = .5 c, and v3 = .7 c. Rank the speed of the light beams from least to greatest as seen by observer next to the track . (TPS) • 1 < 2 < 3 • 1 > 2 > 3 • 1 < 3 < 2 • 1 > 3 > 2 • The speed is the same for all of the light beams

  6. Two clocks will be shown. They will keep time by sending a pulse of light back and forth and counting a tick each time the pulse returns to its starting point. View the operation of the clocks at rest. http://webphysics.davidson.edu/physlet_resources/special_relativity/default.html

  7. The green clock will move with respect to the red clock at a speed of .5 c.Make the following prediction on your own

  8. When the green clock moves with respect to the red clock it will • Keep the same time as the red clock • Run faster than the red clock • Run slower than the red clock • Cannot be determined

  9. Consult with your neighbors and answer again

  10. When the green clock moves with respect to the red clock it will • Keep the same time as the red clock • Run faster than the red clock • Run slower than the red clock • Cannot be determined

  11. The same situation as before only now the clocks are oriented in the direction of travel. Answer the following on your own.

  12. When the green clock moves with respect to the red clock it will • Keep the same time as the red clock • Run faster than the red clock • Run slower than the red clock • Cannot be determined

  13. Consult with your neighbors and answer again

  14. When the green clock moves with respect to the red clock it will • Keep the same time as the red clock • Run faster than the red clock • Run slower than the red clock • Cannot be determined
