For a different Hubble constant, the turning point tTPis different. In this article, we’ll be talking all about acceleration: what it is and how to calculate it. Acceleration is the rate of change of velocity. At any point on a trajectory, the magnitude of the acceleration is given by the rate of change of velocity in both magnitude and direction at that point. The turning point and acceleration expansion of the universe are investigated according\ud to the standard cosmological theory with a non-zero cosmological constant.
