Dynamics

1. Momentum-Impact

   • Used for short duration forces. time not always needed
   • moving object suddenly changes direction
   • Moving and rotating object suddenly changes direction
     • Remember to use the distance perpendicular to COM and POI

2. Energy considerations

   • Use for when there is no time consideration
   • Kinetic Energy
     • Rotational
     • Translational
   • Work
     • Force over a distance. Usually external to the system
   • Potential Energy

3. Force
