Given that , Mass of the body ,m=1 kg Mass of earth m=6xx10^(24) kg Radius of the Earth , R=6.4xx10^(6) m Now , magnitude of the gravitational force (F) bettween the earth and the body can be calculated F=G(Mm)/(r^(2))
How do the units of work and power compare? What is the unit of force in MKS system? What metric unit do we use to denote velocity? A joule is equal to one what times one meter? What are possible correct units for g in the SI system of units?
We define in physics the four fundamental forces which are the weak force, strong force, electromagnetic force, and the gravitational force. The gravitational force is the force of attraction between all masses on earth. This means that any objects are attracting each other because of the ...
What is gravitational force? A. The force that repels objects. B. The force that makes objects transparent. C. The force that attracts objects towards each other. D. The force that makes objects glow. 相关知识点: 试题来源: 解析 C。解析:文章明确指出重力是吸引物体相互靠近的力。A 选项排斥...
The gravitational force between Mars and Phobos is4.6X10^15 N. What is the gravitational force between two forces? Gravitational force -an attractive force that exists between all objects withmass; an object with mass attracts another object with mass; the magnitude of the force is directly propo...
The gravitational force tugging between two bodies depends on how massive each one is and how far apart the two lie, according toNASA Glenn Research Center. Even as the center of theEarthis pulling you toward it (keeping you firmly lodged on the ground), your center of mass is pulling bac...
The Earth exerts enough force to accelerate objects that are dropped at a rate of 9.8 m/s2, or 32 feet/s2. This gravitational force is often referred to as g in equations. If you drop something off a cliff, for each second it falls it will speed up by 9.8 m/s. So, if it falls...
Isaac Newton proved that the force that causes an apple to fall to the ground is the same force that causes the moon to orbit the Earth. This is Newton's Law of Universal Gravitation, which he defined mathematically, using G as the gravitational constant. dmitro2009/Shutterstock Here on th...
The gravitational force is the force that acts between the two objects due to their masses. This force is inversely proportional to the square of the distance between the masses. The gravitational force is proportional to the product of the two masses....
