The shape of the earth's orbit around the sun is essentially a circle. Assuming the earth maintains a constant speed as it orbits around the sun, which statement about the earth's motion is most correct?
a. Its acceleration is zero since it is moving at constant speed.
b. Its acceleration is not zero but is very small.
c. Its acceleration is 9.8 m/s2.
d. Its acceleration is 1.0 m/s2.
I kinda think that the answer maybe D but i'm not to sure.
