gravitational acceleration 相关知识点: 试题来源: 解析 D。本题考查物理学中“重力”的英语表达。选项 A“force”意思是“力”,范围较广;选项 B“weight”指“重量”;选项 C“mass”是“质量”;选项 D“gravitational acceleration”才是“重力加速度”,即“重力”在物理学中的准确表达。
words, light itself, and silence may have no measurable weight, but in a sense they outweigh blocks of metal and rock. Similarly, the great gravitational forces that maintain the complex order of the solar system
Mass Weight Inertia Mass & Weight Mass is the amount of matter in a body. The SI unit of mass is the kilogram (kg). The weight of an object is the amount of gravitational force acting on it. The SI unit of weight is the Newton (N). Gravitational Field A gravitational field is a ...
4.Electric charge is invariant while relativistic mass isn't 2.这条问,把磁铁靠近冰箱的门,磁铁会粘在门上,为什么说磁铁是永久的磁体而冰箱不是.其实是要求你知道source of a permanent magnetic field 的定义. 答案是:Permanent magnets are objects that produce their own persistent magnetic fields.All pe...
Gravitational mass is the property of objects that determines how they interact via gravity. For example how the Moon rotates around Earth. Inertial mass is an object's property that determines how much the object "resists" acceleration when force is applied to it. And it seems both are one ...
more modern, way to state the law is: ‘every point mass attracts every single other point mass by a force pointing along the line intersecting both points. The force is proportional to the product of the two masses and inversely proportional to the square of the distance between the point ...
Mass is the charge of the gravitational interaction and without it nogravitational forceexists. Physicists refer to this manifestation of mass as gravitational mass. When you open a door, you have to push it with a force, otherwise the door won't move. This is because the door has mass man...
Microgravity (微重力) is the experience of gravity that is only a small part of the force we experience on Earth.Gravity is a force(1) which/that attracts anything with mass to anything else that also has mass.The more mass it has,the(2) greater(great) the gravity will be.You can st...
2. A particle P of mass m is above the surface of the Earth at distance x from the centre of the Earth. The Earth exerts a gravitational force on P. The magnitude of this force is inversely proportional to x2.At the surface of the Earth the acceleration due to gravity is g. The ...
