Force field (technology)

A force field is a type of technology that is used to protect something from harm. It is like an invisible shield that surrounds the things it is protecting and keeps them safe. It works like a wall that stops bad things - like, bullets, or bombs, or really anything that might want to hurt - from getting too close, and it doesn't let them through. It is like a force of energy that bounces things away.
