Understand what work done is. State some examples of work being done and no work being done. Calculations involving work done. Energy Energy is the ability to do work. Without energy, machines and people will not be able to do work. The SI unit of energy and work done is joule (J)....
(c) What is the work done by the gravitational force on the sled? (d) What is the total work done? Figure 4. A rescue sled and victim are lowered down a steep slope.Glossaryenergy: the ability to do workwork: the transfer of energy by a force that causes an object to be ...
then energy put into the mower by the person is removed continuously by friction, and eventually leaves the system in the form of heat transfer. In contrast, work done on the briefcase by the person carrying it up stairs
Work-Energy Principle--The change in the kinetic energy of an object is equal to the net work done on the object. Energycan be defined as the capacity for doing work. The simplest case of mechanical work is when an object is standing still and we force it to move. The energy of a m...
1 Energy Transfer by Heat, Work and Mass 2 Objectives • Introduce the concept of energy transfer by heat. • Discuss the various..
Explain work as a transfer of energy and net work as the work done by the net force. Explain and apply the work-energy theorem. Work Transfers Energy What happens to the work done on a system? Energy is transferred into the system, but in what form? Does it remain in the system or ...
Energy, Work, and Transfer of Energy Physical Science Chapter 12. Chapter 5: Work and Energy. Today’s Objectives What do you think? List five examples of things you have done in the last year that you would consider. Chapter 4 Energy ...
so: - no displacement MEANS WORK=0 no transfer of energy - component perpendicular to displacement means WORK = 0 NET WORK DONE on an object = WORK done by the net force. For the suit case: NET FORCE = Fx – fk NET WORK = (Fx – fk) x displacement. Example: Find the net work ...
