Weight and mass are two important concepts in physics; Important and relevant, but totally distinct.
In daily life, the termsWeight is often confused.
mass, amount of matter
Body mass gives an indication of how muchwhich constitutes it. And therefore, It is a directionless and constant quantity – as long as the object does not undergo any change – which is related to number and nature who makes it.
In the international system, the unit of measurement for mass is.
Weight, force related to gravity
The, meanwhile, relates to an act of force on this body. In fact, weight is a quantity that is always directed toward the center (or any other celestial body) which depends on:
- The distance between the body and the Earth (or any other celestial body);
- of the mass of the bodies concerned.
So the weight of the body is higher on the ground than on the ground.
In the international system, the unit of weight is.
bathroom scale secret
However, it should not be concluded that aIt measures your mass, not your weight. In fact, if you jump on the scale, the indicator will increase significantly for a moment. This is a sign that the device is very sensitive to force, and therefore to your weight. Newton was not adopted as a unit of force until the late 1940s. Previously, we used the force of the kilogram, hence the confusion on the scale.
Correlation between mass and weight
If mass and weight are two different quantities, then they are related by a simple expression:
weight = mass xg
where g represents the intensity of gravity, and its value depends on where we are.
