Hello everyone!
When we do work against a field on an object, why must the force we apply on it be equal and opposite to that of the field? If the object is initially at rest, then shouldn't we be applying a force greater and opposite to that of the field to first set it into motion? We could later make it equal after the object has been set into motion, but the first initial push should be greater.
Thank you! :)
