Electrogravitics refers to a fringe scientific theory that suggests a link between electric fields and gravity. As it is a relatively obscure concept, there may not be many commonly used synonyms for the term. However, some related words or phrases might include: electrokinetics, charged particles, electromagnetic forces, gravitational forces, and anti-gravity. While some scientists continue to explore the idea of electrogravitics, it remains a controversial and unproven concept that is often dismissed by mainstream physics. As such, it may not be a term that comes up frequently in discussion or in scientific literature.
