Total work in physics is the sum of all the work done by an object or system. It takes into account both the magnitude and direction of the force applied to an object, as well as the displacement of the object.
Total work is related to potential energy through the concept of work-energy theorem. According to this theorem, the total work done on an object is equal to the change in its kinetic energy plus the change in its potential energy.
When there is no change in potential energy, it means that the object is not moving vertically, and therefore no work is being done against gravity. This results in a zero change in potential energy, and consequently, the total work is also zero.
Understanding total work and ΔPE helps us to understand the relationship between the force applied to an object and its displacement. It also helps us to calculate the amount of work done by a system, which is crucial in various fields of physics, such as mechanics and thermodynamics.
Yes, total work can be negative. This happens when the force applied to an object is in the opposite direction of its displacement. In this case, the work done by the force will result in a decrease in the object's kinetic energy, leading to a negative change in its potential energy.
