1 Newton = 1 kg m/sec2 (A kilogram is the amount of weight at which 1 N of force will accelerate at a rate of 1 m/s2.) --->>English System: Pound (LB) 1 LB = 4.448 N In English system of measurements, a slug is the amount of mass that 1 pound of force will accelerate ...
In general, the force is defined as the derivative of the particle momentum with respect to the proper time. The work of this force during movement of a particle in a constant gravitational field is not consistent with the energy conservation law. The consistency takes place only if the force...
“Mass” is defined as the amount of matter that an object contains. While “weight” represents the force that a mass-containing body exerts on another body purely under the influence of gravity. Mass is impervious to the forces of gravity, weight is the embodiment of this force itself. Re...

A. The object will sink. B. The object will float. C. The object will stay in the same place. D. The object will disappear. 相关知识点: 试题来源: 解析 B。中文解析:“If the buoyant force is greater than the weight of the object, the object will float.”。 反馈...
Suddenly we realize that weight and mass are not the same thing! Away from the earth the force of gravitation changes. As the pull gravitation changes, weight changes, but the mass of an object stays the same anywhere in the universe— whether it is on earth, on the moon, or on Mars....
Weight is a measure of force due to gravity on an object, while density is the mass per unit volume of a substance.
The gravitational force acting on an object at the Earth's surface is called the weight of the object. All the heavenly bodies in space like the moon, the planets and the stars also exert an attractive force on objects. The bigger and heavier a body is, the greater is its force of ...
