1. How would you describe the motion of the vehicle? 2. Did the speed of the vehicle change? How did you know? 3. Did the speed of the vehicle remain the same? How did you know? 4. At which point of the ride did you think the vehicle moved fastest? How about slowest? Or at uniform or constant rate?
Answers & Comments
1.The motion of a car can be described by measuring the distance and time to calculate the speed.
2. Speed continues to be one of the major factors contributing to accidents on Australia’s roads
Even a small reduction in speed can greatly reduce the chance or severity of an accident.
3. If the vehicle moves it will decrease overtime
4. This is related to the first concept in that at the bottom of hills all of the potential energy has been converted to kinetic energy, which means more speed. Likewise, cars always move the slowest at their highest point, which is the top of the first hill.
