About this unitForce fields sounds like science fiction, but they are a part of everyday life. In fact, they're what keep your lights on, your papers magnetically attached to your fridge, and you from floating off into outer space. Learn about electromagnetism, gravity, and how forces can be modeled using vector fields.
If it's massive, then it's attractive.
So that's why long-distance relationships are so complicated.
If we can't see electric or magnetic fields, how can we measure them?
