Question

A satellite is cruising in a stable orbit around earth at a constant speed. Is the satellite accelerating? Why or why not can someone pls explain this to me pls

Answer 1

since its direction is changing, its velocity is changing.
That is acceleration.

Answer 2

You can tell that an object moving in a circle is accelerating because its motion is always changing direction. If you add the object’s momentum and the centripetal force together, the result is circular motion. An object undergoing uniform circular motion is moving with a constant speed, but it is accelerating due to its change in direction. The direction of the acceleration is inwards.
