		Centripetal because it is "center seeking" and radial because it is directed along the radius of the circular path.
		The velocity vector is always tangent to the circular path while the centripetal acceleration is directed toward the center of the circle and perpendicular to the velocity vector.
		Centripetal force is must be provided or supplied by another force and the new name just tells us the direction of the force, as in toward the center of the circle.

	The Starship 2000
		Using the acceleration recorded in the z-axis in Figure 3 as the dominating part of centripetal acceleration that is felt by the rider and the formula below, the maximum number a g’s a rider experiences during this ride can be approximated, which once calculated is approximately 2 g’s.
		Using the resultant acceleration and the relationship ac=gtanø (this relationship is proved in the next section), it is possible to calculate the angle of the wall.
		Determining the centripetal acceleration is similar to the method used to find the resultant acceleration, however, the gravitational acceleration must be taken away from the resultant acceleration to determine the centripetal acceleration.

	The Architecture of Artificial-Gravity Environments for Long-Duration Space Habitation
		The centripetal acceleration vector is aligned along the radius, and the magnitude of the acceleration is proportional to the radial distance.
		However, the centripetal acceleration attributable to the Earth's rotation is incidental to the apparent gravity at its surface (on the order of 0.003 g at the equator, and less at higher latitudes), and variations in height are negligible compared to the average radius from the Earth's center (approximately 720 times the height of Mt. Everest).
		On the other hand, the apparent gravity in a rotating space station will be entirely due to centripetal acceleration (tidal accelerations may play a minor role), the radius will be smaller by a factor of thousands, and the angular velocity will be greater by a factor of thousands.

		The centripetal force is, by definition, the radial component of the net force acting on the body.
		The "measured centripetal force" labels the values obtained by direct static measurement of the force required to extend the spring to that radius.
		That relation tells us that the centripetal force is proportional to the mass and to the radius and proportional to the square of the frequency.

	The Physics of Racing, Part 4: There Is No Such Thing as Centrifugal Force
		The acceleration is proportional to the sideways force, and inversely proportional to the mass of the car, by Newton's second law.
		The sideways acceleration thus causes the car to veer a little sideways, which is what you wanted when you turned the wheel.
		Acceleration is, precisely, the change in velocity over a certain time, divided by the time; just as velocity is the change in position over a certain time, divided by the time.

	The Centripetal Force Requirement
		And in accord with Newton's second law of motion, an object which experiences an acceleration must also be experiencing a net force; and the direction of the net force is in the same direction as the acceleration.
		The passengers lean is not an acceleration in itself but rather the tendency to maintain whatever state of motion they have while the car does the acceleration.
		As the centripetal force acts upon an object moving in a circle at constant speed, the force always acts inward as the velocity of the object is directed tangent to the circle.

		Remember that acceleration in physics is defined as a change in the velocity, not a change in the speed (contrary to the everyday interpretation).
		We derived the magnitude of the centripetal acceleration vector and found it to be constant for uniform circular motion.

	Uniform circular motion
		Centripetal force is a misleading term because, unlike the other forces we've dealt with like tension, the gravitational force, the normal force, and the force of friction, the centripetal force should not appear on a free-body diagram.
		The centripetal force is not something that mysteriously appears whenever an object is traveling in a circle; it is simply the special form of the net force.
		In this case the coordinate system is horizontal and vertical, because the centripetal acceleration points horizontally in towards the center of the circle and there is no vertical component of the acceleration.

	Question_14
		As a reaction force, it is caused by the inward-directed (centripetal) acceleration/Action force, which in turn, is the cause of the activity of the test object's inward-directed (centripetal) acceleration.
		Further, you understand and accept that an inward-directed (centripetal) acceleration/Action force is required to be present and acting as the cause of inward-directed (centripetal) acceleration for each of the turntable's objects.
		The only acceleration that exists in circular events, where an object is rotating about or orbiting an axis at a uniform rate, is inward-directed or centripetal acceleration.

	Physics & Biomechanics Glossary: Centripetal Force
		The acceleration points toward the center of the circle and, in fact, "centripetal" means "center-seeking".
		By Newton's Second Law, such acceleration implies that there must be a force acting on the object, directed at the center of the circle.
		This change in velocity, and the centripetal acceleration, are illustrated in the diagram of a skater skating in a circle.

		The direction of the acceleration is easy to figure: It cannot be along the direction of v, because if it were the magnitude of v would change and, as stated, the object has constant speed.
		Thus the acceleration must be perpendicular to v, and as it clearly is not outward from the center it must be inward.
		The magnitude of the acceleration is another matter.
