Flashcard on Albert Einstein

Front

What is the General Theory of Relativity?

Back

A theory proposed by Albert Einstein that describes how mass can warp space-time, affecting the motion of objects and the path of light.

Front

What is the speed of light according to Einstein's theories?

Back

It is constant and the fastest speed possible in the universe.

Front

What does the equation E=mc^2 represent?

Back

It shows that energy (E) and mass (m) are interchangeable; they are different forms of the same thing.

Front

What does it mean that mass can warp space-time?

Back

It means that massive objects like planets and stars can bend the fabric of space-time, influencing the movement of other objects.

Front

What is the significance of Einstein's theory about the universe's structure?

Back

Einstein proposed that the universe is expanding, which was a revolutionary idea at the time.

Front

What is Special Relativity?

Back

A theory by Einstein that addresses the physics of objects moving at constant speeds, particularly at speeds close to the speed of light.

Front

What is the relationship between energy and mass?

Back

They are interchangeable, meaning that mass can be converted into energy and vice versa.

Front

What is a key concept of light in Einstein's theories?

Back

Light travels in straight lines unless influenced by gravity or mass.

Front

What does it mean for the speed of light to be constant?

Back

It means that light travels at the same speed (approximately 299,792 kilometers per second) in a vacuum, regardless of the observer's motion.

Front

What is the principle of equivalence in General Relativity?

Back

It states that the effects of gravity are indistinguishable from acceleration.
