This weekend I drove out to a big deserted parking lot. I started at one end and accelerated to 20 miles an hour. When reaching 20 miles an hour, I let go of the gas pedal and expected for the car to go at constant velocity like we learn from Newton's laws in physics. But it didn't happen!! The car began to slow down the second I let go of the gas pedal!!
I thought that maybe it was an error in the slope of the road. So I tried again from the other side of the parking lot. But the exact same thing happened! That was when I remembered something from physics: there is the force of kinetic friction and air resistance acting upon the car, slowing it down and making Newton's laws seem flawed. It was a very insightful ride.
By the way, I was just kidding because I would NEVER disregard Newton's laws =)

nikki driving = scary... i like how you accelerated in a parking lot! no where does it mention that you applied the brakes? uh oh.
