Various questions that I've seen have assumed that a Jedi could have/should used their powers at some point, be it force speed, force push etc.
Thinking back to the films, we don't see a gratuitous amount of force use (except where not doing so would be incapacitating, e.g. Yoda the Bouncing Ball of Death) as we might expect from watching people play the various games that go along with the Star Wars universe.
Clearly the jedi in films use a certain amount of restraint. But how much and is this due to specific training/doctrine they hold by, or is it that taxing? Is it different in different films/eras?
