안녕하세요!

Energy & work 강의를 보고 질문이 생겼는데요 - work done by the field = - work done by you 라고 선생님이 설명해주셨는데, 이런 상황에서는 그럼 net work 가 0 되나요? 그럼 change in kinetic energy 는 불가능한가요? 

if the force applied is greater than the force due to the gravitational field (or electric field for e&m), wouldn't there be a difference between the work done by the applied force and the work done by the field?
