Question 1.
What defines an inertial frame?
Show hintHide hint
Think about motion and laws of physics.
Question 2.
State the formula for time dilation.
Show hintHide hint
It involves the moving clock's proper time.
3Question 3.
What is the key characteristic of an inertial frame?
- It accelerates constantly
- Newton's laws apply
- Time is absolute
Show hintHide hint
Think of where you can freely apply physics laws.
4Question 4.
True or False: Time dilation means all clocks run slower in motion.
- True
- False
Show hintHide hint
Consider the effect of relative motion on clock speeds.
Question 5.
Given an observer at rest measures light traveling 300,000 km, how would this distance change if measured from an object moving at half the speed of light?
Show hintHide hint
Use the speed of light in calculations.
Question 6.
A spaceship travels at 0.9c. How would you calculate the proper time for an observer on Earth versus an astronaut aboard?
Show hintHide hint
Proper time is what the astronaut will measure.
