Exit Flashcard: "True or False"

Front

Time moves slower for fast-moving objects.

Back

True. This phenomenon is known as time dilation, a concept from Einstein's theory of relativity.

Front

Time dilation is only a theory, not real.

Back

False. Time dilation is a real effect observed in various experiments and applications.

Front

The concept of time dilation is used to synchronize clocks on satellites.

Back

True. Time dilation must be accounted for to ensure accurate GPS functionality.

Front

Time dilation can be observed in particle accelerators.

Back

True. Particles moving at high speeds experience time differently than stationary observers.

Front

GPS satellites experience time dilation.

Back

True. Their high speeds and gravitational effects cause time to pass differently compared to clocks on Earth.

Front

What is time dilation?

Back

Time dilation is the difference in the elapsed time as measured by two observers, due to a relative difference in velocity or gravitational field.

Front

Who proposed the theory of relativity?

Back

Albert Einstein proposed the theory of relativity, which includes the concepts of time dilation.

Front

What effect does gravity have on time?

Back

Gravity can slow down time, a phenomenon known as gravitational time dilation.

Front

How does speed affect time perception?

Back

As an object's speed approaches the speed of light, time appears to slow down for that object relative to a stationary observer.

Front

What is the significance of time dilation in GPS technology?

Back

Time dilation is crucial for GPS accuracy, as it ensures that satellite clocks are synchronized with Earth-based clocks.
