LEARNING OBJECTIVE 3.3.A - Describe the potential energy of a system. AP MECHANICS -C LEARNING OBJECTIVE CON 1.E -Calculate the potential energy of a system consisting of an object in a uniform gravitational field. In the last section, we derived an expression to calculate the numerical value of kinetic energy. Let’s now derive expressions for potential energy associated with two of the...
LEARNING OBJECTIVE 3.4.C - Describe how the selection of a system determines whether the energy of that system changes. AP MECHANICS -C LEARNING OBJECTIVE CON 1.A -Compare conservative and dissipative forces. Describe the role of a conservative force or a dissipative force in a dynamic system. In the last section, we looked at the case of motion of a ball in the gravitational field and concluded...
LEARNING OBJECTIVE 3.4.B - Describe the behavior of a system using conservation of mechanical energy principles. AP MECHANICS -C LEARNING OBJECTIVE CON 1.A -Compare conservative and dissipative forces. Describe the role of a conservative force or a dissipative force in a dynamic system. In last section, we looked at the law of conservation of mechanical energy. Then we quickly dismissed it in...
LEARNING OBJECTIVE 3.4.C - Describe how the selection of a system determines whether the energy of that system changes. AP MECHANICS -C LEARNING OBJECTIVE CON 2.A -. Describe physical situations in which mechanical energy of an object in a system is converted to other forms of energy in the system. An object thrown into the air with a certain kinetic energy returns to the ground without quite the...
LEARNING OBJECTIVE 3.4.B - Describe the behavior of a system using conservation of mechanical energy principles. AP MECHANICS -C LEARNING OBJECTIVE CON 2.B -. Describe kinetic energy, potential energy, and total energy in relation to time (or position) for a “conservative” mechanical system. In the last section, we introduced a very profound idea of the conservation of mechanical energy...
LEARNING OBJECTIVE 3.4.B - Describe the behavior of a system using conservation of mechanical energy principles. AP MECHANICS -C LEARNING OBJECTIVE CON 2.A -. Describe physical situations in which mechanical energy of an object in a system is converted to other forms of energy in the system. Describe physical situations in which the total mechanical energy of an object in a system changes or...
LEARNING OBJECTIVE 3.3.A - Describe the potential energy of a system. AP MECHANICS -C LEARNING OBJECTIVE CON 1.B -Explain how the general relationship between potential energy functions and conservative forces is used to determine relationships between the two physical quantities. In the last section, we introduced the idea of kinetic energy. Kinetic energy stores work by virtue of motion...
LEARNING OBJECTIVE 3.2.A - Describe the work done on an object or system by a given force or collection of forces. AP MECHANICS -C LEARNING OBJECTIVE INT 4.C -Calculate the net work done on an object that undergoes a specified change in speed or change in kinetic energy. Calculate changes in an object’s kinetic energy or changes in speed that result from the application of specified forces. In...
LEARNING OBJECTIVE 3.1.A - Describe the translational kinetic energy of an object in terms of the object’s mass and velocity. AP MECHANICS -C LEARNING OBJECTIVE INT 4.C -. Calculate the change in kinetic energy due to the work done on an object or a system by a single force or multiple forces. In the last section, we looked at ways to store work. The next obvious question is how to transport this...
LEARNING OBJECTIVE 3.4.A -Describe the energies present in a system. In the last section, we learned to calculate Work in different scenarios. Work makes things happen. The next question is can we somehow store the work for future use, If so how? Once stored we will probably also need to transport it, which will allow us to use it wherever we need as well as whenever we need it. This is the main...
