Energy – forces doing work
WebIn fact, energy can be defined as the ability to do work. Energy can take a variety of different forms, and one form of energy can transform to another. In this chapter we will … WebThis means that there must a relationship between work and kinetic energy. Its relationship with potential energy is dependent on the type of force that is exerted on the system. Conservative forces do work on a system, in a way that is independent of the object's path. It only depends on the displacement of the object.

WebWork is a form of energy. true. A Watt is the standard metric unit of work. false (joule) A kg•m2/s2 would be a unit of work. true. Work is a time-based quantity; it is dependent … WebΔ U. \Delta U ΔU. delta, U. is change in potential energy. The initial mechanical energy of a system equals the final mechanical energy for a system where no work is done by non-conservative forces (conservation of mechanical energy principle). K 0 + U 0 + W NC = K + U or W NC = Δ K + Δ U.
