Seatbelts Why Do Boats Float
Why do boats float? All boats float, but floating is harder and confusing than it sounds and its best explained through a scientific concept called buoyancy. Buoyancy is the force that causes floating. An object will either float or sink depending on its density in the water. If it's denser than water, it mostly sinks; the less dense object usually will float. It doesn't matter the size of the object is. Plastic that is big as a football field will float because it is less dense that the water. A boat mostly floats and it also sinks according to its weight and how much weight it carries with it.

The Federal Government made automakers install automatic restraint systems. This also included the use of shoulder harnesses on the rails and slots that would automatically slide in place when you get ready to start your car. In 1955 a Swedish automaker Volvo was the first manufacturer to make seat belt systems as regular equipment in its cars. In the 1970s the Federal Government required automakers to make automatic restraint systems. This involved the use of shoulder harnesses on rails and slots which would automatically slide into place when the driver has started the car. Along with the seat belts, air bags have been on the rise to. Air bags have reduced the number of fatal and serious automobile injuries in vehicular accidents greatly, particularly in the highway accidents involving higher speeds. In the 1980s American automakers and buckle suppliers began a campaign to develop a seat belt buckle with a tongue ejects feature and a release push button on the end of the buckle, rather than on the side or the top. The next 20 years, the auto industry and federal governments campaign for seat belt laws to be passed in all 50 states. Reports from NHTSA
