Spatial/ Galilean Relativity
Galileo simply described this as the fact that an
observer in motion sees things
differently from a stationary observer
We use this as a part of our everyday
experience
Albert Einstein •German physicist •Developed 2 theories on relativity
1. Special theory of Reality
2. General theory of Reality
•Believed that relativity teaches us the connection between the difference descriptions of one and the same reality
Special Relativity Published in 1905 in Einstein's paper :
On the Electrodynamics of Moving Bodies Deals with things moving near or at the
speed of light Based on two postulates
1. The law of physics are the same in all inertial (non-accelerating) reference frames
2. The speed of light in free space is constant
Einstein’s FormulaRelating mass & energy
Energy = mass times speed of light squaredEinstein’s equation implied that tremendous energies were
contained in small masses
Explanation of the Special Relativity Theory
General Relativity Published in 1915 Explains the force of gravity in terms of curving
four dimensional space-time.According to Einstein the forces of acceleration &
gravity areEquivalent.
This theory is based on one thing1. That all physical laws can be formulated so it can be
valid for any observer, regardless of the observer’s motion
Explanation of General Relativity
