2 cards from this section. Quick, good the night before a test.
What is the equation for the x-coordinate in Galilean transformations?
Think about how the position changes based on relative velocity.
Does time change in different inertial frames according to Galilean transformations?
Recall the assumption of absolute time.
What is the equation for y′ in Galilean transformations?
Note how the motion affects this direction.
In Galilean transformations, is time absolute?
Think about how it pairs with speed.
A train and a car move parallel with the train traveling at 80 km/h and car at 50 km/h. How would a passenger in the train calculate the car’s speed?
Remember to subtract the speed of the slower object from the speed of the faster object.
Two observers are standing on a platform as a train passes by. Observer A indicates the train is 200 meters long, while observer B on the train thinks it's 190 meters. Why the difference?
Think about different perspectives of measurement based on relative speed.
