Concept:Weight is the gravitational force acting on an object due to the Earth's attraction.
Explanation:The weight of an object is caused by the gravitational pull of the Earth.
This gravitational force pulls the object downward, making it press against any supporting surface.
Therefore, when an object rests on the ground, the force it exerts on the ground is the direct consequence of its weight.
In equilibrium, the magnitude of this ground force equals the weight of the object.
Thus, weight is effectively the force that the object exerts on the ground due to gravity.
Answer:The correct option is C: the force that it exerts on the ground.
