Ch work and energy
Web1. Work is the transferring of an energy’s amount via a force through a distance by the direction of the force. Energy is all defined as the ability to push. or pull by exertion in a certain path or distance. 2. An example of Work: A block displaced along a table by force (F) and distance (D). WebTo lift an object slowly, a force equal to its weight (mg) is applied through a height (h). The work accomplished is equal to the change in potential energy: W = P. E. f − P. E. o = mgh f − mgh o , where the subscripts (f and o) refer to the final and original heights of the body. Launching a rocket into space requires work to separate the ...

WebWork is said to be done when a force is applied to make an object move. To do this, energy is required. Also, work can be either positive, negative, or zero. There are different forms of energy, such as kinetic energy, potential energy, heat energy, light energy, chemical energy, sound energy, nuclear energy, and electrical energy.
