* Work in physics: Work is done when a force causes a displacement. In simpler terms, work is done when something moves due to a force acting on it.
* Gravity's influence: Gravity exerts a continuous force on a satellite, pulling it towards the Earth.
* Satellite's movement: Even though a satellite is in orbit, it's constantly moving. The force of gravity changes the direction of the satellite's motion, causing it to travel in a circular or elliptical path.
Therefore, the force of gravity is constantly doing work on a satellite, even when it's in orbit.
Here's a crucial point to remember:
* Work doesn't necessarily mean the satellite is getting closer to Earth. The work done by gravity can change the direction of the satellite's motion, maintaining its orbit rather than causing it to fall down.
Let me know if you'd like me to elaborate on any of these points!
