A prime difference though is how big of an injury it is. People who were wearing seat belts at the time of a crash are less likely to have serious injuries, while those who weren't wearing seat belts have a higher possibility of sustaining really serious injuries.
Pendulum under goes energy conversions from potential to kinetic and back to potential.
A pendulum consists of a long string to which a bulb is attached. The string is fastened to a point from which it can oscillate freely when displaced through a small angle.
The pendulum is an example of a system in which energy conversion takes place. The energy is converted from potential to kinetic and back to potential. Since the image was not shown in the question, we can not locate the specific points where the energy conversions occur.
