SPECIAL THEORY OF RELATIVITY

Question 1

The idea was introduced and revolutionized by Albert Einstein

Answer 1

Time Travelling

Question 2

detects changes in position over time, essentially perceiving motion. In physics, a body encompasses any entity, whether macroscopic or microscopic.

Answer 2

Observer

Question 2

Everything around us is connected

Answer 2

CLASSICAL RELATIVITY

Question 2

It was first introduced using the concept of Newtonian Mechanics

Answer 2

CLASSICAL RELATIVITY

Question 3

All motions are relative to a particular frame of reference.

Answer 3

Newtonian Mechanics

Question 4

is where motion is observed, whether an object is at rest or in motion. All motions are connected within a particular frame of reference.

Answer 4

Inertial Frame of Reference

Question 4

aligns with the law of inertia and can be either stationary or in uniform motion.

Answer 4

Inertial Frame of Reference

Question 5

——- believed that the speed of an electromagnetic wave in the form of light must be constant regardless of the identified inertial frame of reference

Answer 5

James Clerk Maxwell

Question 5

states that the motions of an object are relative to the inertial frame of reference. Hence, things move relative to each other - no absolute rest and motion.

Answer 5

Special Theory of Relativity (STR)

Question 6

Also known as Galilean Invariance

states that the laws of motion are the same in all inertial frames.

Answer 6

GALILEAN RELATIVITY

Question 6

Involves bodies experiencing changes in velocity, deviating from constant motion.

Answer 6

Non inertial frame of reference

Question 6

asserts that the laws of motion apply universally without exceptions. According to this principle, the speed of an object is not constant and will vary depending on the chosen frame of reference.

Answer 6

GALILEAN RELATIVITY

Question 6

It states that the speed of light in a vacuum must be the same in all inertial reference frames

Answer 6

Einstein’s Postulates: The Constancy of the Speed of Light

Question 7

is the “slowing down” of a clock as determined by an observer who is in relative motion with respect to that clock.

Answer 7

Time Dilation

Question 7

states that simultaneity is not absolute but depends on the observer’s frame of reference.

Answer 7

Relativity of Simultaneity

Question 8

It states that the laws of motion are the same in every inertial frame of reference.

Answer 8

Einstein’s Postulates: The Relativity Principle

Question 9

is the phenomenon where a clock appears to slow down as observed by an observer who is in relative motion with respect to the clock.

Answer 9

Time Dilation

Question 10

It tackles that the length of an object is relative to the observer’s inertial frames of reference.

Answer 10

Length Contraction

Question 11

demonstrates that the length of an object is relative to the observer’s inertial frame of reference, akin to time and simultaneity.

Answer 11

Length Contraction

Question 12

it tells us that no ordinary matter or entity known to exist in the observable universe can travel faster than 300 million meters per second except light.

Answer 12

Cosmic Speed Limit

Question 13

It states the equivalence between mass and energy. The product of a large value of the squared speed of light and a small amount of mass corresponds to a tremendous amount of energy released during a nuclear reaction.

Answer 13

Mass-Energy Equivalence
