Weight is the combination of mass and gravity: Weight = Mass x Gravity Your weight depends on the gravitational pull of the Earth. If you were standing on Mars, your weight would depend on the gravitational pull of Mars, and therefore, you would have a different weight. Your mass, on the...
Since the weight WW of an object is the gravitational force acting on it, and the acceleration due to gravity is equal to the gravitational field strength gg, by Newton’s Second Law of Motion, F =m × aF =m × a where, FF is the resultant force mm is the mass of an object aa ...
If the postulate that the gravitational and inertial mass of a test body are equal is broken, then test bodies of of different inertial masses will have different accelerations in a gravitational field. Therefore, Einstein wouldn't be able to abstract the gravity field as a property of the bod...
A. gravity B. mass C. distance D. gravitational constant 相关知识点: 试题来源: 解析 D。本题考查对万有引力定律中字母含义的理解。在公式 F = Gm1m2/r²中,G 代表万有引力常量(gravitational constant)。A 选项 gravity 是重力;B 选项 mass 是质量;C 选项 distance 是距离。反馈...
I frequently get emails wanting to know whether gravity is a law or a theory. That question brings up so many more questions that I thought it would be fun to explore. To try this, you will need: - an object to drop. OK, pick an object that will not brea
What Is Gravity? Every object that has mass exerts a gravitational pull or force on every other mass. The strength of this pull depends on the masses of objects at play. Gravity keeps the planets in orbit around the sun and the moon around the Earth. Hence, we define gravity as: Gravity...
In fact the intensity of the gravity field (the force acting on the unit mass) with the unit N/kg is the generally needed quantity instead of the acceleration. Its use will be suggested also in geodesy and proper units in the SI system will be recommended for gravity potential, ...
aThe earth's gravity field is almost the same as that of a sphere having the same average radius and total mass but increases slightly towards the poles. In gravity surveys, gravimeter measures gravity differences ,not absolute field strengths. 地球的引力场轻微地几乎是相同象那球形有同样平均半径...
