questions
1. why are car tires moving at 30 m/s experience four times greater forces than when moving at 15 m/s (or half the speed)?
2. What is meant by average velocity?
3. How can you tell if the speed or velocity is constant?
4. How do you change from one unit to another?
5. what is the difference between positive and negative acceleration?
