I did not have too many people at office hours this week. All of the questions were about the new material. People had trouble understanding the difference between impulse and momentum. This was difficult to explain because rhis was new material that students had not had time to understand the material. The easiest way for me to explain the concepts was to start with F=ma and derive the equations. This is not the best way to provide a good understanding of the concept but this is a good place to start. I think one way to help students is to provide real life examples of impulse like a ball hitting a baseball bat.
