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. ...
"The difference between centripetal and centrifugal force has to do with different 'frames of reference' — that is, different viewpoints from which you measure something," saidAndrew A. Ganse, a research physicist previously at the University of Washington. "Centripetal force and centrifugal 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...
Does centripetal force change the normal force? Does centripetal force cause acceleration? 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...
有什么力当你站在地心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 wer
That's clever. Kids won't get confused at all. Did you know that the earth doesn't need centripetal force as it doesn't spin fast enough in relation to its diameter?. You got it at 1000mph is not fast enough because it only does one revolution in 24 hours, and you need revolutions...
v: is a speed that satisfies the centripetal force equation. The relevance of the particles central motion of force: Many natural phenomena define the central force in Physics. Some of the examples are; Planets that revolve around the sun. Natural satellites that are travelling across the earth...
An example of circular motion is the moon orbiting the Earth. As the moon orbits, it is under a force resulting from thegravityof the Earth. This means it’s constantly “falling” toward the Earth and, therefore, has a centripetal acceleration pointing toward the center of the Earth, even...
b) If this same force is applied to a 4.2 kg object, what acceleration is produced? How can a small force impart the same momentum to an object as a large force? Does centripetal force affect velocity? How to calculate the force constant ...
The family culture values make the family members to be easier to form the common goal, and to realizes the goal constitution intense centripetal force and the cohesive force. [translate] a首先保证乘客的安全,然后用最周到的服务直到到达目的地 First guaranteed passenger's safety, then until arrives...
