centripetal force

## centripetal force

n.
The component of force acting on a body in curvilinear motion that is directed toward the center of curvature or axis of rotation. Centripetal force is necessary for an object to move with circular motion.

## centripetal force

n
(General Physics) a force that acts inwards on any body that rotates or moves along a curved path and is directed towards the centre of curvature of the path or the axis of rotation. Compare centrifugal force

## centrip′etal force′

n.
the force, acting upon a body moving along a curved path, that is directed toward the center of curvature of the path and constrains the body to the path.

centripetal force
Centripetal force causes the ball being whirled at the end of a string to move in a circle about the person, and not to fly out and away along the path of inertia.

## cen·trip·e·tal force

(sĕn-trĭp′ĭ-tl)
The force that pulls an object moving in a circle toward the center of the circle and causes the object to follow a curving path. Earth's gravity acts as a centripetal force on the moon.
Did You Know? In one popular carnival ride, people stand with their backs against the wall of a cylindrical chamber. The chamber spins rapidly and then the floor drops out, but the riders remain pressed against the wall and don't fall down. Why? Most people would say that the reason people "stick" to the wall is because a centrifugal, or outward, force is pushing them against it. In actuality, there is no outward force, no matter how strongly the people on the ride may think they feel one. In fact, it's just the opposite: the riders are really subject to an inward, or centripetal, force. As the ride spins, it forces the riders to travel in a circle. Objects (including people) in motion tend to travel in a straight line at constant speed unless they're acted on by some external force. To make an object travel along a curved path, you have to keep forcing it toward the "inside" of the curve. The walls of the ride do just that, pushing the riders toward the center; the friction between the riders and the wall holds them up, so they seem to defy gravity.

## centripetal force

A force that acts radially inward on an object moving in a circular path.

It is not enough that we should have matter, we must also have a single impulse, one shove to launch the mass and generate the harmony of the centrifugal and centripetal forces. Once heave the ball from the hand, and we can show how all this mighty order grew.'--'A very unreasonable postulate,' said the metaphysicians, 'and a plain begging of the question.
As the air I breathe is drawn from the great repositories of nature, as the light on my book is yielded by a star a hundred millions of miles distant, as the poise of my body depends on the equilibrium of centrifugal and centripetal forces, so the hours should be instructed by the ages and the ages explained by the hours.
Under the centripetal force, the base of the projectile tended toward the moon; but the centrifugal still prevailed; and it was probable that its rectilineal course would be changed to a curve of some sort, the nature of which they could not at present determine.
What I think of on this point is, when self is the fixed point the centripetal force is balanced with the centrifugal.

At the same time, however, there were centripetal forces at work creating a larger, if sporadic, Panhellenic cultural identity: the Greek language (despite dialectical variations), the pantheon of Greek deities, the Homeric poems as a common cultural possession, and the great religious festivals with the most famous, of course, being Olympia--for which the Greeks would call a sacred truce in order to send representatives to compete in the musical and athletic contests.
