I need to find the radial acceleartion of the Earth @ the equator
a=v^2/r
a= [1041m/s)^2]/6378000m
a= 0.17 m/s^2
is this correct?
a=v^2/r
a= [1041m/s)^2]/6378000m

Radial acceleration of the earth is the acceleration of the earth towards the center of its orbit around the sun. It is also known as centripetal acceleration and is caused by the gravitational force between the earth and the sun.
Radial acceleration can be calculated using the formula a = v^2/r, where a is the radial acceleration, v is the speed of the earth in its orbit, and r is the distance between the earth and the sun.
The value of radial acceleration of the earth varies depending on the distance between the earth and the sun. On average, it is about 0.0059 m/s^2, which is significantly smaller than the acceleration due to gravity on the earth's surface.
Radial acceleration plays a crucial role in keeping the earth in its orbit around the sun. Without it, the earth would move in a straight line tangentially to its orbit and eventually drift away from the sun.
No, radial acceleration is not the only force acting on the earth. The earth also experiences tangential acceleration due to its rotation on its own axis and other forces such as the gravitational pull of other planets and the moon. However, the radial acceleration is the dominant force in the earth's orbit around the sun.
