Exploring Time Dilation in IB Physics

Which movie is referenced at the beginning of the tutorial?

• Back to the Future

• Inception

• Interstellar

• The Matrix

What does the term 'dilation' imply in the context of time dilation?

• To contract

• To expand

• To remain constant

• To oscillate

According to the tutorial, how can you travel forward in time?

• By moving at a constant speed

• By moving at a speed close to the speed of light

• By staying stationary

• By moving backward in time

What is the term used for the time measured by a frame where events happen at the same place?

• Universal time

• Proper time

• Absolute time

• Relative time

What is the Lorentz factor (gamma) used for in the time dilation equation?

• To measure speed

• To measure distance

• To account for relativistic effects

• To measure mass

In the example, what speed is the spaceship traveling at?

• 0.7 times the speed of light

• 0.5 times the speed of light

• 0.9 times the speed of light

• 1.0 times the speed of light

What is the calculated proper time for the journey in the example?

• 6.45 years

• 4.36 years

• 2.29 years

What happens to the age difference between the traveler and the people on Earth after the journey?

• The traveler does not age

• Both age the same

• The traveler ages less
