Question

what happens when a force is applied to a part of an object? the object changes color the object becomes heavier the object stops vibrating the object bends or deforms

Explanation:

Force can cause an object to change its shape or size, which is called deformation. Color change is not a direct result of applying force, an object's mass doesn't change just due to applied force (mass is an inherent property), and an object doesn't stop vibrating as a direct result of applying a general - purpose force (it might start vibrating or change its vibration state).

Answer:

The object bends or deforms
