A reflex is a natural movement brought on by a particular stimulus.
<h3>What is stimulus?</h3>
A stimulus in physiology is a perceptible alteration in the physical or chemical composition of an organism's internal or external environment. Sensitivity refers to an organism's or organ's capacity to recognize external stimuli and respond appropriately (excitability). As with touch receptors in the skin or light receptors in the eyes, sensory receptors can pick up information from both within and outside the body. Chemoreceptors and mechanoreceptors are examples of internal sensory receptors. A stimulus can trigger a response via stimulus transduction when it is recognized by a sensory receptor. The first element of a homeostatic control system is frequently an internal stimulus.

Well,
Let's just say that the Jaguar! (a certain ride in Knott's) could instantly go from zero speed to, let's say, 40 mph, and vice versa. We know (if you have ridden it) that the Jaguar! is not a straight line, as you can't say that it is always traveling at 40 mph due north (otherwise it would never be able to make a loop)!
Remember that, since velocity is a vector quantity, a change in direction will constitute a change in velocity.
