The coupling means comprise control stiffness means, for instance an elastic element, so that when the probe contacts the object, the displacement of the lever is proportional to the force exerted by the probe on the object. Such control stiffness means are tunable so that the accuracy and ...
C. The force exerted by gravity on an object is not related to its mass. D. The force E. xerted by gravity on an object is equal to its volume. 相关知识点: 试题来源: 解析 B。解析:“The results of our experiment showed that the force exerted by gravity on an object is directly ...
就是和一个平面垂直的力。Normal force翻译过来是正向力，你也可以叫它支持力。但是支持力可能不是单方向，其中和平面垂直的component才是normal force."In mechanics, the normal force Fn is the component, perpendicular to the surface of contact, of the contact force exerted on an object by,...

The force exerted on a polarizable object due to the intensity gradient of the blackbody radiation can be derived from the same fluctuation electrodynamic formalism as the temperature-dependent Casimir–Polder force25,26. Conventionally, thermal Casimir–Polder forces are considered in planar geometry, ...
2. strength exerted upon an object; physical coercion; violence: to use force to open a door. 3. strength; energy; power: the force of the waves; a personality of great force. 4. power to influence, affect, or control; efficacious power: the force of circumstances. 5. Law. unlawful ...
Thus, since the moon is a smaller body than the Earth, the force it exerts on an object at its surface is less than that exerted by the Earth on the same object on the Earth's surface. In fact, the moon's gravitational force is only one-sixth that of the Earth. This means that ...
