Is centripetal force the same as circular motion? Does centripetal force change the normal force? What provides the centripetal force when a car drives in a circle? Suppose you exert a force of 157157 N tangential to a 0.2740.274-m-radius 7272-kg grindstone (a ...
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...
a seat on a swing), the centripetal and centrifugal are equal in magnitude, but opposite in direction. The centripetal force acts on the body in motion, while the centrifugal force does not. For this reason, centrifugal force is sometimes called a "virtual" force. ...
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...

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 ...
In my view, I have offered a wide-ranging but eminently coherent framework-in-progresssomewhere between parochialism and the most promiscuous forms of eclecticism. In Hermans's terms, I have sought to provide a centripetal force in an intellectual environment that has experienced too much of the ...
The minimum speed for it to just move in a complete circle is when T at the top is zero ie when mg on its own provides the centripetal force.You need to use conservation of energy and momentum. hmm. why energy is conserved? i thought this is perfectly inelastic ...
