Unformatted text preview: that kinetic energy can be translational or rotational. Also when writing the gravitational potential energy of a rigid body, consider its mass as being concentrated in the center of mass. 4. when there is a collision or the moment of inertia of the system changes, apply the conservation of angular momentum 5. don't forget to always connect the rotational and translational motions if you have both: v=(omega)R and a=(alpha)R 6. Always figure out if you have a point particle or a rigid body, and use the proper equations. 7. Universal gravitation problems deal either with forces, or energy, or angular momentum 8. If the three laws do not work, start the problem from the definitions of quantities required. Good luck! Your instructor, Dorina Kosztin...
