Thanks for answering my question guys. It's really helpful.

Correct me if I'm wrong.Since the force can't travel in vacuum like for instance the gap between the sun and the earth. Isn't it more practical if we just say gravity only instead of gravitational force?

According to Einstein's theory it is the bending of space that keeps the Earth moving on its orbit around the sun and not any invisible force. Why they still teach gravitational force in school ?
