Centripetal and centrifugal forces are two terms used to describe the physics of circular motion — but only one of them is real. The centripetal force keeps an object moving in a circle and is always pointed toward the center of that circle. For instance, the gravitational force of the sun...
Centrifugal force is what keeps a string with a ball on the end taut when you whirl it around. A centrifuge is a machine that uses centrifugal force. At the end of a washing machine's cycle, it becomes a weak and simple centrifuge as it whirls the water out of your clothes. Centrifug...

The concept of centrifugal force is taught in elementary science education, sometimes even before Newton's Laws are introduced. However, centrifugal force fails to explain orbit, weightlessness, weight, or "artificial gravity" in a way that is consistent with Newtonian physics. In terms of the ...
aSince on the surface, centrifugal force is larger than pressure gradient force, but on the bottom, the pressure gradient force is larger than centrifugal force. 因为在表面,离心力大于迫使梯度力量,但在底部,压力梯度力量大于离心力。[translate]...
force that is always perpendicular to the direction of motion will make the object move in a circle. it is important to note that centripetal force is still some force. for instance, suppose you swing a rock around your head with a string. there is a force acting on the rock to make ...
Centrifugal force is the force which describes the outward pressure that is exhibited around an object rotating around a central point. Its definition is based on a Latin phrase which means "fleeing the center," an accurate description based on what is being observed. There are some physicists ...
blades are (a) forward curved (Figure 18-136D), in which case the kinetic energy and the centrifugal force velocity of the rotating wheel/blades of these two velocities are additive; or (b) curved backward, in which the velocities oppose each other, and the result is less than the forwar...
As the wheel spins faster the force increases. Because the main wheel and outer wheels always point in one direction the main wheel would always be imbalanced in that direction, the faster the wheel turns the more centrifugal force on the one direction the weights are pointing, thus creating ...
