Who formulated the Theory of Relativity?
Click to flip
Albert Einstein.
Click to flip
What are the two parts of the Theory of Relativity?
Click to flip
Special Relativity and General Relativity.
Click to flip
What does the Special Theory of Relativity primarily deal with?
Click to flip
The physics of moving bodies at speeds close to that of light.
Click to flip
What is the speed of light in a vacuum?
Click to flip
Approximately 299,792,458 meters per second (or about 300,000 kilometers per second).
Click to flip
What is the famous equation associated with the Special Theory of Relativity?
Click to flip
E=mc².
Click to flip
What does E=mc² represent?
Click to flip
Energy equals mass times the speed of light squared; it shows the equivalence of energy and mass.
Click to flip
What concept does General Relativity introduce about gravity?
Click to flip
Gravity is not a force but a curvature in spacetime caused by mass.
Click to flip
What is spacetime?
Click to flip
A four-dimensional continuum that combines the three dimensions of space with the dimension of time.
Click to flip
How does mass affect spacetime according to General Relativity?
Click to flip
Mass curves spacetime, causing objects to follow curved paths.
Click to flip
What is Time Dilation?
Click to flip
A difference in elapsed time as measured by two observers, due to a relative velocity between them or a difference in gravitational potential.
Click to flip
What real-world technology uses principles from the Theory of Relativity?
Click to flip
Global Positioning System (GPS) which accounts for time dilation.
Click to flip
What experiment confirmed the theory of General Relativity?
Click to flip
The 1919 solar eclipse experiment observing the deflection of starlight by the Sun's gravity.
Click to flip
What is Length Contraction in relativity?
Click to flip
The phenomenon where an object in motion is measured to be shorter along the direction of motion from the viewpoint of a stationary observer.
Click to flip
How does the Theory of Relativity affect our understanding of the universe?
Click to flip
It provides a more accurate model of physical processes at an astronomical scale and near light speeds.
Click to flip
Why is the Theory of Relativity considered revolutionary in physics?
Click to flip
Because it changed the previously held notions of absolute time and space, providing new insights into gravity and the universe.
