Weight is the mass of an object times the acceleration due to gravity or mg. This is a shortcut for the more precise equation, which is Newton's law of gravitation. This equation can be used to determine the weight of an...
The weight?Gravity:In reference to the Gravity, the bending of the space-time because of the mass of the lump imposes a force of attraction over the other lump which is also present in the space-time. Heavier the lump is, more will be the force of attraction....
While mass is measured in kilograms, a unit that is also used for weight, there is a difference between mass and weight. An object's weight (w) is defined by its mass (m) times the acceleration of gravity (g), expressed in the formula w = mg. This means that when gravity changes,...
The mass of an object of density ρ at that size scale is M(ρ)∼ρℓ3, and the total mass of objects with density between ρ and ρ+dρ is simply ρp(ρ)dρ, where p(ρ) is the PDF of the density, which is trivially related to the PDF p(s) of the log of density. ...
Every object has a gravity wavelength, and for the object being acted upon, classical type gravity occurs at distances less than its gravity wavelength while wave gravity occurs at distances greater than its gravity wavelength. The theory yields a set of 8 logarithmic singularities in the gravity ...
another chronometric instrument, excluding a gravity pendulum which cannot work in outer space. The “ruler” is a length-measuring tool in the physical sense; some examples include a meter stick or another instrument that measures dimensions. “Mass” is inertial mass, an object measured by its...
GR is a successful theory of gravity. However, at large scales, it cannot explain why our universe is undergoing an accelerated cosmic expansion. This is one of the reasons why GR needs to be modified. Among various modified theories of gravity, massive gravity can describe the late-time acce...
"The mass and gravity of asteroids are not great enough to make them a sphere."语法正确吗?make them a sphere, them表示是复数,但后面跟a sphere,可以吗?make them spheres 觉得很别扭。 关注者8 被浏览824 关注问题写回答 邀请回答 好问题 添加评论 分享 登录...
In a conservative system in which only the conservative force or forces work, the total kinetic energy (the potent energy plus the kinetic energy) of an object always remains constant.Answer and Explanation: Given The mass of the object...
The density of an object can be defined as the ratio of the mass of the object and the volume of the object. The density is used to measure the compactness of the object. Typically, the density of the object is measured in Kilogram per cubic meter....
