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...
What is kinetic energy?
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...
Can we store work – What is Energy?
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...
Work done in case of varying force
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.B -Calculate a value for work done on an object from a force versus position graph. Consider a body moving in a straight line under the influence of force F. For simplicity, we assume that displacement of the body happens in the direction of...
Work done by a force acting at an angle with displacement
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.A -Describe the work done on an object as the result of the scalar product between force and displacement. Explain how the work done on an object by an applied force acting on an object can be negative or zero. Having considered the simple...
Calculating work done by a force
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.A -Calculate work done by a given force (constant or as a given function F(x)) on an object that undergoes a specified displacement. let’s now define the work mathematically, so that we can calculate its value. To introduce the...
