What is weight ?
object on Earth we can define weight as follows:
Weigth is the gravitational action exerted by Earh upon this object.
can also be defined for objects on other celestial bodies. For
instance, on the Moon the weight is the gravitational action exerted by
the Moon upon an object.
- Axis and
If an object is dropped it falls down along a vertical axis.
The weight has the same properties: it is exerted along a vertical axis
the Earth's scale, the weight is exerted following the direction of
terrestrial radius, toward its center.
- The weight value:
The weight value is denoted W. It is expressed in newton ( symbol: N )
measure weight using a dynamometer.
