Concept Card: Work Done by Constant & Variable Forces & Kinetic Energy 1. Physical Definition of Mechanical Work: Work is done by a force when its point of application undergoes a displacement having a non-zero component along the line of action of the force. Work Done by a Constant Force ($\vec{F}$): Defined as the scalar … Read more

1. The Physics Definition of Work In everyday language, “work” implies physical or mental effort. In physics, work has a highly specific, mathematically rigorous definition: Work is done when a force causes a displacement, and there is a component of the force in the direction of the displacement. If a constant force $F$ acts on … Read more
