What is TIDAL ACCELERATION or TIDAL DECELERAION? Also, could some one please explain me it's forumlae?
Tidal acceleration is the phenomenon where the gravitational pull of the moon and sun causes the Earth's oceans to bulge, creating high and low tides. This force also causes the Earth to rotate slightly slower, resulting in an increase in the length of a day over time.
Tidal acceleration occurs due to the gravitational force between the Earth and the moon and sun. The moon's gravitational pull is stronger on the side of the Earth facing the moon, while the gravitational force on the opposite side is weaker. This difference in force creates the bulge in the Earth's oceans and results in the Earth's rotation slowing down.
The formula for tidal acceleration can be expressed as a = GM/R^3, where G is the gravitational constant, M is the mass of the moon or sun, and R is the distance between the Earth and the moon or sun.
Tidal acceleration causes the Earth's rotation to slow down by about 2 milliseconds per century. This is because the Earth's rotation is slightly decelerated by the gravitational pull of the moon and sun, causing the length of a day to increase over time.
In addition to slowing down the Earth's rotation, tidal acceleration also causes the moon to slowly move farther away from the Earth. This can also have an impact on the Earth's orbit and the distance between the Earth and the sun, although these effects are very small.
