The Newton Car
So, you calculated the linear momentum of the empty Newton car while it was at rest, and you found it to be equal to 0 kg(m/s) because any object which is not moving has a momentum equal to zero.
Now, with nothing on the Newton car, use a match, lighter, or scissors to break the string and release the rubber band. Note: If you use a match or lighter to break the string, you can light either of the string's loose ends like a fuse. If you use a pair of scissors to break the string, make sure you move the scissors immediately after cutting the string.
After you break or cut the string, answer the question in the poll below.
