Weight, gravitational force of attraction on an object, caused by the presence of a massive second object, such as the Earth or Moon. Weight is a consequence of the universal law of gravitation: any two objects, because of their masses, attract each othe
The equation also indicates the weight of an object (W = mg).The major feature of this force is that all objects fall at the same rate, regardless of their mass. Gravity on the Moon and on other planets have different values of the acceleration due to gravity. However, the effects of ...
of the force of gravity on a given body is theweightof that body; although the mass of a body does not vary with location, its weight does vary. It is found that at any given location, all objects are accelerated equally by the force of gravity, observed differences being due to ...
The force of gravity makes things fall to the ground. “gravity” means ___. A. heavy B. weight C. pull D. attraction 相关知识点: 试题来源: 解析 D。“gravity”是重力,即一种吸引力,与“attraction”意思相符。“heavy”是重的;“weight”是重量;“pull”是拉。反馈...
Gravity is also what gives weight to objects on Earth and keeps us from floating away. It pulls everything towards the center of the Earth, keeping us firmly on the ground. The strength of gravity depends on two things: how big an object is and how far apart objects are. If something ...

on an object from a distance. That’s the reason they are non-contact forces. The strength of gravity is an attractive force that is exerted by the Earth on objects, which makes them fall to the land. The weight of a body is the force that is pulled by the earth towards the centre...
Gravity is a force of attraction that exists(存在) between any two objects in the universe. It makes planets go around the sun and creates stars and galaxies(星间系). Gravity is also what gives weight to objects on Earth and keeps us from floating away. It pulls everything towards the ...
of a body is the primaryconsideration, it is generally valid as well as convenient to assume that the forces are concentrated at a single point. In the case of gravitational force, the totalweightof a body may be assumed to be concentrated at its centre of gravity (seegravity, centre of)...
