    "In physics, force is what causes a mass to accelerate. It may be experienced as a lift, a push, or a pull" - wikipedia

    No offense, but these are pretty basic definitions that you could find easily with a little effort. Do you have a text? What does it say about forces?

    I'll give you a hint: If you can find Newton's Second Law in your text, it should answer all three of these for you.
