we are currently learning that F=ma. what does F= delta P/ Delta t stand for? thats cool about your son and daughter. what colleges did they go to? What are your children planning to be when they graduate? Most of use are undecided, but we will probably end up going to the community college. A used to live in Illinois for 3 years. Have you ever been to Chicago? Have you ever been in a tornado before? would you ever want to study them?

Hi,
Newton actually first described his second law in terms of momentum. He said that for an object to have its momentum altered (mass time velocity) then a force has to be applied over a certain length of time. So, F= delta P/ Delta t means that the force is equal to the change in momentum divided by the change in time. But it isn't often introduced that way these days, at least not in High School physics.
My daughter is at Purdue University in Indiana, and my son is at a local community college here where we live, near Chicago. She is studying hotel management, and he is studying emergency medicine to become a paramedic.
I've been to Chicago many, many times. It is a really beautiful city, one of my all-time favorites. I've attached a photo of Chicago taken (not by me) from the top of the Fermilab main building. It was taken at sunset one day of the year when the sun reflects off of the buildings directly back toward Fermilab.
I have not ever seen a tornado. But I've seen first-hand what they can do, and have been close before! I'm not sure I'd be up to studying them up close, though!-Mike
