hey i'm a highschool student which majors in science (physics) and to pass my grade i need to make an essay paper including the problem, experiments, and of course conclusion. But I can't make up my mind of what topic should I make. And one thing that gave me an idea is about car safety, does a safety belt really save you in an accident or does the shape or position could harm you in a large impact. Any suggestion of what should I make? The problems and possibly how should I do the experiment with because I ain't gonna crash my car for the experiment, is there any easier way to test this? thankyou so much if you're willing to help :) ps: or maybe about the car's centre of gravity and how it effects the safety of it in a crash.
