Weight
Mass is the amount of matter in an object. Mass remains unaffected by gravity. Weight is a measure of the gravitational pull on an object and is therefore affected by gravity.
Basically it is the object's "weight". The gravitational force on an object is its Mass X Gravitational Constant. The gravitational constant is the acceleration of a free falling body towards another body, and on Earth is equal to 9.81 meters/sec2 or 32.2 feet/sec2. Thus while the MASS of an object is a constant physical property, the WEIGHT of an object depends on the local gravity field pulling on that MASS.
effort, resistance
Measurement is a process of comparison between a certified standard or a calibrated measuring instrument and the object or the material to be measured (analyzed). For example, to measure a weight you compare the weight of an object with the calibrated weights of a balance.
The force would be the weight of the object.
To measure weight, a scale. To measure mass, a balance.
Weight is the measure of the earth's pull of an object.
using the light alone to measure the weight of a unknown object is impossible.
The mass of an object does not change , but its weight can vary.
The object's weight is the measure of the gravitational force on that object.
Weight
That is called the object's WEIGHT.
the WEIGHT of the object.
Mass is a measure of how much matter an object has. Weight is a measure of how strongly gravity pulls on that matter.
The force of gravity between the Earth and an object on its surface is what we call the object's "weight". What is not generally appreciated is that the object attracts the Earth toward it with the same force. This means that whatever your weight is on Earth, it's the same as the Earth's weight on you.
"Weight" is a measure of gravitational force acting on an object.
