Question: What is the acceleration of an artificial satellite moving in orbit around the Earth?

1) Equal to zero 2) Directed along the tangent to the orbit 3) Directed towards the center of the Earth 4) Directed towards the poles of the Earth

The acceleration of an artificial satellite moving in orbit around the Earth is directed towards the center of the Earth.

When an object moves in a circular orbit, its direction of motion is constantly changing as it travels around the circle. Therefore, it experiences a constant acceleration towards the center pointed at the center of the orbit, which in the case of satellites orbiting the Earth is the center of the Earth. This acceleration is due to the gravitational force exerted by the Earth, which pulls the satellite towards its center.

The acceleration is not zero, as the satellite's velocity and direction of motion are changing constantly as it orbits the Earth. It is also not directed along the tangent to the orbit or towards the poles, but specifically towards the Earth's center, which is the source of gravitational attraction responsible for keeping the satellite in its orbital path.
