Topic 3.4: Conservation of Energy
Boundary Statements official exam scope notes
- AP Physics 1 expects students to know that mechanical energy can be dissipated as thermal energy or sound by nonconservative forces.
Learning Objective: 3.4.A
Describe the energies present in a system.
Essential Knowledge: 3.4.A.1
A system composed of only a single object can only have kinetic energy.
Essential Knowledge: 3.4.A.2
A system that contains objects that interact via conservative forces or that can change its shape reversibly may have both kinetic and potential energies.
Learning Objective: 3.4.B
Describe the behavior of a system using conservation of mechanical energy principles.
Essential Knowledge: 3.4.B.1
Mechanical energy is the sum of a system’s kinetic and potential energies.
Essential Knowledge: 3.4.B.2
Any change to a type of energy within a system must be balanced by an equivalent change of other types of energies within the system or by a transfer of energy between the system and its surroundings.
Essential Knowledge: 3.4.B.3
A system may be selected so that the total energy of that system is constant.
Essential Knowledge: 3.4.B.4
If the total energy of a system changes, that change will be equivalent to the energy transferred into or out of the system.
Learning Objective: 3.4.C
Describe how the selection of a system determines whether the energy of that system changes.
Essential Knowledge: 3.4.C.1
Energy is conserved in all interactions.
Essential Knowledge: 3.4.C.2
If the work done on a selected system is zero and there are no nonconservative interactions within the system, the total mechanical energy of the system is constant.
Essential Knowledge: 3.4.C.3
If the work done on a selected system is nonzero, energy is transferred between the system and the environment.
