 The {{w|Slingshot|slingshot}} (in this comic, styled "Regular Slingshot") is primarily refering to the hand-held device used for accelerating small projectiles, such as stones or steel balls. The "forked stick and elastic" contraption (known as a catapult, in the UK) acts by a pull-back-and-release action, and has become associated with youthful recklessness (or an outright tendency towards vandalism), but is also the basis of manufactured sport/hunting devices as well as all of the more organic child-made contraptions.

		+
		+	The '''gravitational''' slingshot, or {{w\|gravity assist}}, is not a device but a term used to describe how gravity can significantly alter the path of an object in space, such as a spacecraft or an asteroid. A gravitational slingshot generally involves a small object passing by a much more massive object, which turns the smaller object's trajectory, trading momentum and kinetic energy between the two bodies. The smaller object can undergo a large change in velocity, "paid for" (in the sense of conserving the momentum and energy of the system) with a negligible change in the velocity of the more massive body.
		+
		+	This comic humorously compares the two, in tabular format.

		+	An other form of {{w\|Sling (weapon)\|stone flinging hand-held weapon}} had existed since ancient times, and has been used for personal defense and for hunting game such as squirrels, birds and {{w\|Goliath\|Philistines}} through skillful use of its mechanical advantage and rotation. It is essentially a mimimalist hand-held form of {{w\|trebuchet}} (using the the thrower's arm as a much more versatile main beam, taken back to mechanical extremes in some proposed {{w\|SpinLaunch\|kinetic energy space-launch}} ideas), compared to the version that is more of a cut-back {{w\|crossbow}}-like 'catapult' (as well as partially duplicating the mechanics of a {{w\|ballista}}), but had necessitated the easy availability of an elastic cord before it could become the common form of slingshot/catapult that then became the signature toy/tool/weapon of both Dennis Mitchell (the American version) and his British namesake (see below).
