Natiijada casharka
I can describe changes to a satellite’s speed and velocity and explain what happens to its orbital radius if its speed changes.
Muuji qoraalka
Artificial satellites orbit Earth because of the gravitational attraction between them.
The speed of a satellite along its orbit around Earth is constant.
The velocity of a satellite along its orbit around Earth constantly changes as it changes direction.
The centripetal force on a satellite makes it accelerate and change direction, but not speed.
To orbit in a stable orbit, the orbital radius of a satellite must change if its speed changes.
