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. ...
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. 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 equation for displacement as a function of time? The moon revolves around the earth in 27.3 days in a nearly circular orbit with a radius of 3.8 \times 10^5 km. Assume that the moon's motion is uniform. In what directi...
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....
The 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.Answer and Explanation: Become a Study.com member to unlock this answer! Create your ...
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.
In the centripetal force equation, what is the mass equal to? Does centripetal force depend on mass? A centripetal force of 245 N acts on a 1,400-kg satellite moving with a speed of 4,500 m/s in a circular orbit around a planet. What is the radius of ...
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...
