text: First of all linear and angular momentum are two different things altogether.It doesn't follows from what you have said that linear momentum = angular momentum.\nIn any case you will always have to multiply the linear momentum by 'r'  to get the angular momentum.\n\nMomentum = m*v\nEnergy /distance   * time = Force * distance /distance  * time\n=Force * time=mass * acc  * time = mass* velocity \nSo  you are correct dimensionally\n\nEnergy* Space * time=energy *distance * time\n=Force * distance* distance *time\n=mass* vel *distance^2  so this isn't momentum\n\nCurvature of space time will have units of 1/(space time)\n\nFind out yourselves whether next two are correct \n\nCurvature of gravitational mass ??\nYou probably mean curvature caused by mass.\nI am not sure of this part though .In any case curvature will have units of (1/space time)\n\n\nJust remember\nConservation of energy follows from isotropy of time \nConservation of momentum follows from isotropy of space
