3. ## Moment and Torque

What is the difference between Moment and Torque ?
4. ## sicar

what does sicar mean? sicar=half tuition scholarship is it true?
5. ## rigid and solid

elasticmodulus = stress/strain is it true?
6. ## A and B barrels

Two similiar barrels A and B with the same radius and mass roll down the same slope starting at the same instant.Barrel A is filled with liqued water, and barrel B is filled with ice of equal mass(Barrel B slightly longer than barrel A to compensate for the slightly larger density of liquid water) which barrel reaches the bottom of the slope first? and why?
7. ## rigid and solid

what is the difference between solid and rigid (in physics) for example, a rigid object ..a solid object
8. ## rain

I know its a dumb question but I wonder.. Which keeps you drier , walking or running in the rain? in other words, do you get wetter if you run or walk in the rain? .(the distance stable) and why?

why not dot or comma why not circle et cetera.. why string?
10. ## The Physical Basis of the Direction of Time

well, What does - t stand for in physics ? -t , travel back in time ?
11. ## The Physical Basis of the Direction of Time

we go any further, it's important to get a clear idea of what time reversal symmetry really means. At the simplest level, we may think of the laws of physics as equations involving a time variable , and say that they are symmetric under time reversal if given any solution, and making the substitution , we obtain another solution. http://math.ucr.edu/home/baez/time/time.html What does t (and - t) stand for in physics ? only time ?
12. ## Novikov self-consistency principle

I understand, that is, this principle says that if an event exists that could give rise to a paradox, then the probability of that event happening is zero.. Is it logic ?
13. ## Novikov self-consistency principle

what is Novikov self-consistency principle?
14. ## yang-mills
