Chapter 7: Motions at high speed
Terms in this set (13)
when we define motion, we always do so with reference to something else. That "something else" also has its measure of motion with reference to something else, etc. e.g. us > earth > sun > galaxy > etc
Does not exist. It is defined with respect to some place that is absolutely at rest.
The idea that motion is only defined relative to other motions. There is no such thing as an "absolute" motion measured against objects that are absolutely at rest.
Inertial Frame of Reference
A perspective that is experiencing no acceleration.
Non-inertial Frame of Reference
A perspective that is undergoing an acceleration.
The Laws of Mature remain the same for all observers in inertial frames of reference.
The General theory of Relativity
The science that studies non-inertial frames of reference
The notion that a final speed vector can be computed by directly adding all individual velocity vectors together. It says that separate velocities combine together to form a total velocity. Light does not obey this law.
The Special Theory of Relativity
The theory of how objects in inertial frames of reference behave at high speeds.
A situation of logic contrived to illustrate a particular effect.
The slowing of a clock as its speed approaches the speed of light as measured by an observer not moving with the clock. we measure moving clocks as running slow. Time really slows down for the object accelerating.
The shortening of an object along its direction of motion as its speed approaches the speed of light, as measured by an observer not moving with the object. When we measure the lengths of objects moving past us, we find their lengths to be shorter than if we measured their lengths while traveling with them.
A happening that occurs at a particular point in space and at a definite time.
