Public Service Announcements

I my science class everyone had to make a Public Service Announcement or P.S.A. on the safety of doing something and the science behind it. I did the safety of wearing proper gear while riding a motor cycle. A lot of people talked about inertia, force, momentum, and Newtons first law, and friction. From my classmates I learned that momentum is the force an object gets while it is in motion. Also I learned that friction is the rubbing between two different objects, force is a push or pull motion, and Newtons law is that whatever is at rest stays at rest unless acted on by an outside force and whatever is in motion stays in motion unless acted on by an outside force. Another thing I learned was how dangerous things are that we do in our everyday life. I think it is very important to know the science behind accidents. That is because if you don't know what happens when there is an accident you could think that it was the person who jumped out of the car window when they actually flew out of the window because they wanted to stay in motion. If they didn't know that force waspushing people oout of a window they might not have made seat-belts or air bags which saves lives. So, yes it is very important to know the science behind crashes.
