UNIT 04 - CONSERVATION OF ENERGY

3. Conservation of Energy
A) Students should understand the concepts of mechanical energy and of total energy, so they can:
 (1) State and apply the relation between the work performed on an object by non-conservative forces and the change in an object’s mechanical energy (C 4.17)
 (2) Describe and identify situations in which mechanical energy is converted to other forms of energy (C 4.18)
(3) Analyze situations in which an object’s mechanical energy is changed by friction or by a specified externally applied force (C 4.19)
B) Students should understand conservation of energy, so they can:
(1) Identify situations in which mechanical energy is or is not conserved (C 4.20)
(2) Apply conservation of energy in analyzing the motion of systems of connected objects(C 4.21)
(3) Apply conservation of energy in analyzing the motion of objects that move under the influence of springs (C 4.22)
(4) Apply conservation of energy in analyzing the motion of objects that move under the influence of other non-constant one-dimensional forces (C 4.23)
C) Students should be able to recognize and solve problems that call for application both of conservation of energy and Newton’s Laws (C 4.24)
4. Power - Students should understand the definition of power, so they can:
(A) Calculate the power required to maintain the motion of an object with constant acceleration (e.g., to move an object along a level surface, to raise an object at a constant rate, or to overcome friction for an object that is moving at a constant speed (C 4.25)
(B) Calculate the work performed by a force that supplies constant power, or the average power supplied by a force that performs a specified amount of work (C 4.26)
