Special Relativity

Explore how time, distance, simultaneity, and speed behave when everyday assumptions no longer hold.

Start chapter

Learning Path

Checkpoint 1

frame

Study two or three interactives, then answer the concept checks before moving on.

Checkpoint 2

time

Study two or three interactives, then answer the concept checks before moving on.

Checkpoint 3

speed

Study two or three interactives, then answer the concept checks before moving on.

Adaptive Suggestion

If this chapter feels hard, study the first few interactives and use the concept checks until your streak improves. If it feels easy, jump to resources with videos or OSPSG links and explain the model evidence in your own words.
