Crash Test without seat belts. Forces on a watermelon. Forces and Movement

With this video you will realise why seat belts are so important in our cars. They can save lifes and we must know that the power of forces can be very dangerous in car accidents.

Look at this video and realise  the effort rubber bands do on a mellon. Of course your real shight misses lots of frames and images we don't see very well. Here you can see how contact forces affect objects, the flexible rubber bands produce a contact force on the watermelon and after placing lots of rubber bands the fruit doesn't resist the force of the rubbers.
