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...
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...
LEARNING OBJECTIVE 3.2.A - Describe the work done on an object or system by a given force or collection of forces. Consider a man holding a ball in a fixed position in his outstretched hand (Refer to Figure case A). Our intuition suggests that the man does work. Yet the equation $W= F.\Delta x $ indicates that no work is done on the ball since the ball does not move and the displacement $\Delta...
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...
LEARNING OBJECTIVE 3.2.A - Describe the work done on an object or system by a given force or collection of forces. In the last section, we look at a new physical quantity called work. We will now go a bit deeper to get the essence of it. Before, we start studying the Work in more detail and mathematically. Let’s try to understand why the work is an important physical quantity. Let us say we...
LEARNING OBJECTIVE 3.2.A - Describe the work done on an object or system by a given force or collection of forces. So far we have handled mechanics problems using force and Newton’s law. Now it’s time to switch to another method of analysing mechanics problems, namely the work and energy method. This method is often easier to use and can provide quick and neat solutions to mechanics problems if...
