Centripetal force may be considered the center-seeking force. Its direction is orthogonal (at a right angle) to the motion of the body in the direction toward the center of curvature of the body's path. Centripetal force alters the direction of an object's motion without changing itsspeed. ...
Does centripetal force equal energy? Is centripetal force the same as normal force? Does centripetal force equal tension and gravitational force? Does centripetal force equal tension? Is centrifugal force the force of reaction of centripetal force? Does normal centripetal force depend on speed? Is ro...
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...
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,这个合力就是向心力....
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...
is very simple. If you swing a ball on a piece of string the ball "exerts" a centrifugal force on you hand, your hand, in its turn, exerts a centripetal force on the ball. You can see from this the ball is "exerting" a centrifugal force, it is not subject to such a force. ...
What are Forces？(力的相互作用-美国康菲尔高中)
