Activity 73 Title: Choosing a Safe Vehicle Problem: Is the rugged strong vehicle (#1) or the quick responsive vehicle (#2) safer? Hypothesis: If a consumer was buying a car based on safety, then the ____________ would be the safest vehicle. Place in upper right hand corner on every page of the activity

Car Accident What comes to mind when you hear this term? The leading cause of death by unintentional injury for ages 1–44 is motor vehicle accidents. The most common ages of people killed in motor vehicle crashes are 15–24 and over 75. Why do you think these age groups have the most fatalities?

What do car accidents have to do with science? The study of motion is important in efforts to improve automotive safety and save millions of lives. Understanding the physics of how and why cars move helps auto engineers design better cars and can help drivers operate cars more safely.

What measurements do you think scientists and engineers find useful when studying car safety and accidents? Force Speed Acceleration
