This is the question in my homework:

Question

In orbiting the Earth, what kind of motion is it, uniformly velocity, uniformly accelerated or non-uniformly accelerated motion?
I have searched for almost an hour on the internet in any variety of those terms I could think of, and I still have found nothing on these subjects. Would someone be able to help me with this? Thanks.

Answer 1

Since the accleration vector keeps changing direction (always pointing to the center of the Earth), satellite motion is nonuniformly accelerated motion.
