Homework Help: Gravity question

  1. Nov 2, 2006 #1
    If I made a planet that was smaller than Earth's and thus had a lesser gravitational pull, would I be able to reach a point of gravity where the object wouldn't completely touch the surface but would instead float just above the surface?

    What object? What else do you know about the planet? I will assume you are talking about some small object (compared to the planet). What do you think will happen based on what you know about gravity?

    This question makes no sense at all. In a vacuum all matter possesses some gravity and thus would be attracted to each other. So, you could not make an object small enough to allow another object to float above its surface.
