Special Relativity Quiz

Who created the Special Theory of Relativity?

• Galileo Galilei

• Albert Einstein

• Nikola Tesla

• Isaac Newton

How do we measure time?

• By looking at some phenomenon that repeats itself

• By using a ruler

• By measuring the speed of light

• By observing the stars

According to Newton, what was the nature of time and space?

• Not relevant to physics

• Absolute and fixed

• Dependent on the observer

• Relative and changing

What are the two postulates made by Einstein in the Special Theory of Relativity?

• The speed of light is constant, and time is absolute

• The laws of physics are absolute, and the speed of light is relative

• The laws of physics are different in different frames, and the speed of light is variable

• The laws of physics have the same form in all inertial frames, and the speed of light is constant

How do we synchronize clocks in different frames?

• By using a ruler

• By setting them to read the same time

• By measuring the distance between them

• By observing the stars

What is the formula for time dilation in Special Relativity?

• t' = t / (1 - v^2/c^2)

• t' = t - vt/c^2

• t' = t - v/c

• t' = t / √(1 - v^2/c^2)

What is the effect of time dilation on the lifespan of a muon traveling at 3/5 the speed of light?

• It will last 50% longer

• It will last 25% longer

• It will last 100% longer

• It will last 75% longer

What is the prediction of Relativity regarding the length of objects in the direction of their motion?

• They contract

• They expand

• They become infinite

• They remain unchanged

According to the Lorentz Transformation, what happens to the time in S' frame as the speed v gets closer to the speed of light c?

• It remains the same

• It becomes infinite

• It becomes negative

• It becomes larger and larger

What is the relativistic factor in the Lorentz Transformation?

• γ = 1 - v/c

• γ = 1 / √(1 - v^2/c^2)

• γ = 1 - v^2/c^2

• γ = 1 + v^2/c^2
