Explain why you are tackling it this way.Quanta,Short answers, MC (
Might do the quick multiple choice questions first...leaving out all the harder ones till later.What order is everyone doing the exam tomorrow?
In all my exams I've done, quanta had been the easiest so I finish it first which increases my motivation, then short answersExplain why you are tackling it this way.
I'll probably be doing a similar approach:Might do the quick multiple choice questions first...leaving out all the harder ones till later.
Then do all the quick short answer questions.
Then do the longer short answer questions and the 6/7/8 marker.
Do the Option (apart from 6/7/8 marker)
Finish Multiple Choice
Do 6/7/8 marker from Option
lv is the length viewed by the observer that is not at the rest frame of reference while lo is, same thing with m and vGUYS! URGENT HELP NEEDED.
I've forgottn how to do relativity questions like time dilation/mass increase/length contration.
I don't know what to make lo , vo and mo and what to make l, v ,m ??
HELP!!
calc l(v) = 1.7x10^5 etcso what about this question. Is 1.7 x 10^5 the lv or lo value??
It's Lo, do you have the answers to check?so what about this question. Is 1.7 x 10^5 the lv or lo value??
i though that lv was the moving frame and the earth is moving relative to you??calc l(v) = 1.7x10^5 etc
yeah soz, worded it badlyi though that lv was the moving frame and the earth is moving relative to you??
Special Relativity is a special case of relativity where you always assume constant velocity (so only considering inertial frames of reference).Difference between relativity and Special relativity???
Assuming you mean galilean relativity, its only applicable at lower, non-relativistic speeds (e.g. addition of velocities which you learn in moving about)Difference between relativity and Special relativity???
The theory of relativity states that the laws of physics are the same for all inertial frames of reference; it is impossible to conduct a physical experiment within an inertial frame without reference to an external point. The principle of special relativity revolves around the concept of relativity, however also states that the speed of light is constant for all frames of reference (3x10^8m/s) regardless of the observer's motion.Difference between relativity and Special relativity???
You also consider the effects of gravity (as a 4D space-time continuum) in General RelativitySpecial Relativity is a special case of relativity where you always assume constant velocity (so only considering inertial frames of reference).
In General Relativity, you consider the general case of non-constant velocities, so the frames of reference are non-inertial. General Relativity is much harder than Special Relativity.
So what does this question actually mean?
Remove the parts for special relativity from his answer and elaborate more on the frames.The theory of relativity states that the laws of physics are the same for all inertial frames of reference; it is impossible to conduct a physical experiment within an inertial frame without reference to an external point.
