Test 3 will cover the material presented in modules 8 through 10.
You must be able to:
 | Use the equation of rotational kinematics to describe the motion of an object under constant angular acceleration. |
| Find the moment of inertia about an axis of a simple system of point masses. |
| Find the angular acceleration and the change of the angular momentum produced by a torque. |
| Find the torque produced by a force. |
| Use conservation of angular momentum to solve physics problems. |
| Find the kinetic energy of rotating objects. |
| Solve for the forces and torques acting on an object in static equilibrium. |
| Use Kepler's laws to analyze orbital motion. |
| Work problems concerning the motion of objects exhibiting simple harmonic motion. |
| Describe transverse and longitudinal harmonic waves mathematically and give the relation between wavelength, frequency, and speed. |
| Analyze standing waves on a string and standing sound waves in tubes with one or two open ends. |
| Qualitatively describe water waves, tsunamis, and tides. |
| Find the wavelength of an EM wave given the frequency and vice versa. |
| Identify different regions of the electromagnetic spectrum. |
| Relate the amplitude of an EM wave to its intensity and to the radiation pressure. |
| Find the Doppler shifted frequency the observer measures when source or observer are in motion. |
Prepare for the test by reviewing assignments 16-22.
