Special Relativity Flashcards
What is Newton’s first law?
Objects in motion (or at rest) remain in motion unless external force imposes change.
What is Newton’s second law?
Force is equal to the change In momentum per change of time.
For a constant mass, force equals mass times acceleration. (F=MA)
What is Newton’s third law?
For every action there is an equal and opposite reaction.
What does “C” mean
C = The Speed of light
299 792 458 m/s
What famous scientist came up with the Theory of Relativity?
Albert Einstein
What two principles make up the theory of special relativity?
The principle of relativity and the principle of the speed of light.
According to the theory of relativity, the speed of light in a vacuum is ______ for all observers?
The same.
Before the theory of relativity, what did scientists with a reference point for all motion?
Ether.
In the equation E= mc2 what does m stand for?
m stands for mass.
In the equation space E=mc2, What does ‘c’ stand for?
‘c’ stands for speed of light
If the mass of an object Changes, what will also change?
The energy will also change.
The foster an object is moving in relation to an observer, the _____ it will appear to an observer.
It will appear shorter to the observer.
