1. Lorentz Factor, g

2. There was a young lady named Bright
Who traveled much faster than light,
She departed one day
In a relative way
And returned on the previous night.

3. Length Contraction

4. The length of the object is measured to be shorter when it is moving relative to the observer than when it is at rest.

6. There was a young fencer named Frick,
Whose thrust was exceedingly brisk,
So fast was his action
The Lorentz contraction
Reduced his rapier to a disk.

7. A rectangular billboard in space has the dimensions 10mx20m
A rectangular billboard in space has the dimensions 10mx20m. How fast and in what direction with respect to billboard would a space traveler have to pass for the billboard to appear square?

8. Relativistic Momentum

9. Mass and Energy

11. The law of conservation of energy is also valid for relativistic velocities.
