W = 980N. The weight of an object of 100Kg in the Earth is 980N.
The weight is a measure of the gravitational force acting on an object, the weight is equivalent to the force exerted by a body on a point of support, caused by the action of the local gravitational field on the mass of the body.
it can be defined as the product of mass by the acceleration of gravity, w = mg. Since weight is a force, its unit is the Newton N.
If the mass of an object on earth is 100 kg, then is weight is:
W = (100Kg)(9.8m/s²) = 980N.
