Using information about natural laws explain why some car crashes produce minor injuries and others produce catastrophic injuries

My main reason would be momentum – it depends on the mass as well as the speed of the colliding objects. For example if two sedans travelling in a low speed bump each other, then probably the damage would be minimal scratches. However, if a high speed car crashes unto a heavy truck also travelling fast, then the result would be catastrophic. 

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
