Flashcards R1
Cards in this deck (9)
- 1—We can sketch out a graph of an
object’s motion (position vs. time)
by plotting the “blink events” that
occur along the object’s path. - 2—A reference frame visualized as a cubical
lattice with a clock at every lattice intersection.
- 3—The aftermath of a collision between two protons in the Large Hadron Collider. The computer reconstructs the particle tracks
by collecting and interpreting data about particle detection events in the detector. This represents an act of “observation.”
- 4—A cross-sectional view of a floating-ball first-law detector. Electrically actuated “fingers” hold the ball initially at rest in the spherical container. After the fingers are retracted, the ball should continue to float at rest in the container, as long as the frame to which the container is attached is inertial.
- 5—An isolated object at rest in the Other Frame must move at a constant velocity with respect to the Home Frame, so the whole Other Frame must move at the
same constant velocity relative to the Home Frame.
- 6—A schematic drawing of two reference frames in standard orientation. The spatial origins of the frames coincided at t = t′ = 0
just a little while ago.
- 7—The relationship between r and r′
for two inertial reference frames
(assuming that time is universal
and absolute).
- 8—An example illustrating the application of the principle of relativity in Newtonian physics. Newton’s second law describes
the motion of the ball in both frames.
- 9—A light flash chasing a departing
spaceship
