Understanding Einstein's Relativity

What does Einstein's special theory of relativity suggest about the speed of light?

• It is constant for all observers, regardless of their motion.

• It is faster for stationary observers.

• It varies depending on the observer's speed.

• It slows down for moving observers.

Which equation is used to calculate time dilation in special relativity?

• L = L0 * sqrt(1 - v^2/c^2)

• ts = tm / sqrt(1 - v^2/c^2)

• F = ma

• E = mc^2

What is the significance of the general theory of relativity?

• It is only a theoretical concept with no real-world application.

• It is unrelated to special relativity.

• It only applies to objects moving at the speed of light.

• It incorporates gravity into the spacetime framework.

How does special relativity contribute to the functioning of GPS systems?

• By ignoring the effects of time dilation.

• By ensuring the speed of light is variable.

• By using Newtonian physics for calculations.

• By factoring in time dilation for accurate positioning.

In the given example, what is the observed length of a meter stick moving at 0.8c?

• 0.4 meters

• 0.6 meters

• 0.8 meters

• 1 meter
