  2. If anybody is still looking for the answers to this quiz, I got a 100 with these answers:
    1. False

    On number 9, give an example in change of velocity. The change of velocity is known as acceleration, and it is the rate at which velocity changes. The change can be speed, direction, or both. So if you were driving at 50 mph and sped up to 55, you would be accelerating 5 miles per hour. Get it?
