Introducción a la RELATIVIDAD ESPECIAL y GENERAL para BACHILLER o PREPARATORIA

The video explores Einstein's 1905 papers, focusing on the special theory of relativity and its foundations in Galileo's principle. It discusses the concept of inertial frames, Maxwell's equations, and the ether. Einstein's postulates are introduced, leading to the loss of simultaneity and time dilation. The video concludes with general relativity, the equivalence principle, and the implications for gravity and black holes.

What was one of the key outcomes of Einstein's 1905 publications?

• The discovery of the electron

• The formulation of the theory of evolution

• The development of the special theory of relativity

• The invention of the steam engine

What did the Michelson-Morley experiment aim to detect?

• The speed of sound in air

• The presence of the ether

• The gravitational pull of the moon

• The temperature of the sun

According to Einstein's first postulate, how do the laws of nature behave for observers in inertial frames?

• They are only applicable to stationary observers

• They change with the observer's position

• They are identical for all observers

• They vary depending on the observer's speed

What is a consequence of Einstein's second postulate regarding the speed of light?

• The speed of light is slower in water

• The speed of light is constant for all inertial observers

• The speed of light varies with the observer's speed

• The speed of light is faster in a vacuum

What phenomenon is demonstrated by the thought experiment involving a light clock?

• Time dilation

• Length expansion

• Mass increase

• Energy conservation

What is the effect called when an object's length appears shorter in the direction of motion?

• Time dilation

• Energy loss

• Length contraction

• Mass reduction

How do muons provide evidence for the theory of relativity?

• They disintegrate instantly

• They travel faster than light

• They reach the Earth's surface due to time dilation

• They are unaffected by gravity

What principle did Einstein propose to explain the indistinguishability of gravity and acceleration?

• The uncertainty principle

• The equivalence principle

• The conservation principle

• The principle of inertia

What astronomical phenomenon did Einstein's theory of general relativity accurately predict?

• The orbit of the moon

• The precession of Mercury's orbit

• The expansion of the universe

• The formation of black holes

What did Eddington's 1919 experiment during a solar eclipse demonstrate?

• The sun is made of helium

• Light is unaffected by gravity

• Light bends around massive objects
