Question

fill in the blank question
when an object is resting on a table in earths gravitational field, the surface of the table exerts a
contact force on the surface of the object.
this force, called the
force, is equal and opposite to the objects weight, keeping the object in equilibrium.

Explanation:

When an object rests on a table, according to Newton's third law, the table exerts a contact force. This force is called the normal force. The normal force is perpendicular to the surface of contact (the table - object interface here). It balances the weight of the object (which is the force due to gravity acting on the object) when the object is in equilibrium (at rest).

Answer:

normal
