Special Relativity

1
Special Relativity

• Theory describes motion in non-accelerating
  reference frames and in the absence of
  gravitational fields
• The theory is based on the following principles
• The laws of nature are the same for everyone.
• The speed of light is the same for everyon.

Consequences of Special Relativity

• Nothing travels faster light
• Time Dilation
• Length Contraction
• Two simultaneous events in one reference frame
  will not be simultaneous in a fast moving
  reference frame
• Energy, momentum, and mass are related

16
Equivalence Principle

• The effects on motion due to gravity are
  indistinguishable from the effects of uniform
  acceleration

Consequences of General Relativity

• Mass generates spacetime curvature. Gravity is
  the consequence of spacetime curvature.
• Time measurements are affected by gravitational
  fields.
• Black Holes
• The Universe has no boundary or center.
• Rapid motion by large masses cause gravitational
  waves.
