	[[Gravity]] is an example of a conservative force. A child turns the same amount of [[gravitational potential energy]] into kinetic energy from going down a spiral slide, a straight slide, or jumping off the slide. Friction is a [[non-conservative force]]—the friction down the slide does negative work on the child, slowing her down, and no work if she jumps (which is why it's safer to slide down a slide then jump off the top).
