Learning Goal: To learn the definition and applications of angular momentum including its relationship to torque. By now, you should be familiar with the concept of momentum, defined as the product of an object's mass and its velocity: pโ =mvโ . You may have noticed that nearly every translational concept or equation seems to have an analogous rotational one. So, what might be the rotational analogue of momentum? Just as the rotational analogue of force Fโ , called the torque ฯโ , is defined by the formula ฯโ =rโ รFโ , the rotational analogue of momentum pโ , called the angular momentum Lโ , is given by the formula Lโ =rโ รpโ , for a single particle. For an extended body you must add up the angular momenta of all of the pieces. There is another formula for angular momentum that makes the analogy to momentum particularly clear. For a rigid body rotating about an axis of symmetry, which will be true for all parts in this problem, the measure of inertia is given not by the mass m but by the rotational inertia (i. e., the moment of inertia) I. Similarly, the rate of rotation is given by the body's angular speed, ฯ. The product Iฯโ gives the angular momentum Lโ of a rigid body rotating about an axis of symmetry. (Note that if the body is not rotating about an axis of symmetry, then the angular momentum and the angular velocity may not be parallel.)

Two conductors, a and b, are each in the shape of a tetrahedron. but of different sizes. they are charged in the following manner: 1. tetrahedron a is charged from an electrostatic generator to charge q. 2. tetrahedron a is briefly touched to tetrahedron b. 3. steps 1 and 2 are repeated until the charge on tetrahedron b reaches a maximum value. if the charge on tetrahedron b was q/4 after the first time it touched tetrahedron a. what is the final charge qbmax on tetrahedron b?

Which of these statements best explains how the hydrosphere interacts with the atmosphere to affect global climate? mountains block rain clouds and cause changes in global rainfall and evaporation. humans burn fossil fuels to produce greenhouse gases which cause global warming. humans cut down trees which affects the amount of oxygen in different parts of the globe. greenhouse gases, like carbon dioxide, dissolve in oceans and prevent global warming.
