Newton's Theory of Gravity states that every object in the universe pulls on every other object. Every object feels this force, so it is a universal force. The force is always attractive; it is always a pull, never a push. Picture the force of gravity as the tension in an imaginary rope between two objects.
The whole point of a USB drive is to store lots of data in a small space, so think about what kinds of files you'll want to house on your flash drive.
