Driving on a Road Trip

This weekend my family and I took a trip down to Fordham University down in the Bronx. As I was driving, I realized all the physics involved in the trip! The car was traveling at a constant speed of 70 miles per hour when it was set on cruise control. On the thruway, the car was only traveling horizontally therefore, it had no vertical distance. the car remained on a straight path where only the horizontal distance was changing. It took us about 5 1/2 hours to get all the way to New York city. Over that time and at that constant velocity, the total distance could be calculated. However, due to traffic and speed limit changes, the car was not traveling at a constant velocity the entire time. Newton's first law states that an object in motion tends to stay in motion unless acted upon by a net force. If I were to stop pressing the gas pedal, the car would continue to move along due to Newton's Law. The friction of the road acts as the net force of the car and would cause the car to eventually stop moving.

Great post -- and how'd you like Fordham?

I loved it! I stayed with the team and talked with the coaches so it was a good weekend!
