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...
求向心力的公式就是向心力(centripetal force)没错,答得好再加悬赏分 真正问题是:what forces act on you were you at the centre of the earth? 相关知识点: 试题来源: 解析 向心力是没有公式的!有公式就是骗人的!为什么呢?因为向心力的定义就是: 作圆周运动的物体,它运动的时候的合力指向圆心,这个合...
Force is everywhere and it comes in a variety of sizes, directions, and type. We can define Force as the push or pull of an object. Learn Force definition, unit & types of Force with solved examples.
A. Centripetal force. B. Centrifugal force. C. Contact force. D. Non-contact force. 相关知识点: 试题来源: 解析 C。原因:推箱子是接触力,A 选项向心力是使物体做圆周运动的力;B 选项离心力是虚拟力;D 选项非接触力如重力、磁力等。涉及的物理知识是力的分类,英语阅读技巧是理解“push a box”这个...

What is the nature of gravitational force?Gravitational ForceThe gravitational force is the force of attraction between two bodies which is inversely proportional to the square of the distance between the bodies and directly proportional to the product of their masses....
A body is able to follow a circular path when a net force called centripetal force is applied on it. A centripetal force has to pull the bodyinwards... Learn more about this topic: Uniform Circular Motion | Formula & Examples from

As the moon orbits, it is under a force resulting from the gravity of the Earth. Centripetal acceleration is a vector, which means it has both a magnitude and a direction. The direction always points inward to the circle's center, because this is the direction in which a rotating object ...
Centripetal force is defined asthe forceacting on a body that is moving in a circular path that is directed toward the center around which the body moves. The term comes from the Latin wordscentrumfor "center" andpetere, meaning "to seek." Centripetal force may be considered the center-see...
