At what point in an elliptical orbit is the acceleration maximum? At what point is it minimum? Justify your answers.
Where do you expect acceleration due to gravity to be larger (and why): at the poles or at the equator?
What is the acceleration of the Earth to stay in its nearly circular orbit around the Sun? Assume the radius of the orbit is 150,000,000 km, and the time to complete an orbit is 365 days.
Pick those answers that apply.
About 6 m/s2 away from the Sun (compare to "g" near Earth which is 9.8 m/s2)
Exactly the acceleration needed to maintain a closed curved and elliptical orbit year after year.
The Earth is not accelerating, it is moving at a constant velocity.
Much smaller than "g" and away from the Sun.
About 6 m/s2 toward the Sun (compare to "g" which is 9.8 m/s2)
