There are three laws in motion that explain movement, they are the Newton’s three laws of motion named after Isaac Newton. The Newton’s first law states that an object that is a rest will stay at rest unless an outside force is acted upon it and an object that is in motion will stay in motion unless an outside force is acted upon it. This is also called as “inertia”, which means the property of an object to restrict its motion. Examples of inertia would be when a car is driving at a constant speed and instantly stops the person will fall forward if there is no seat belt.

The seat belt is a safety device that is commonly found on car seats and aircraft seats, it is made from strong durable materials such as fabric, nylon or polyester. Cars that are manufactured are required to have seat belts due to road safety laws. The law was introduced in the 1970s, it was shown that having seat belts reduced the amount of road deaths. The seat belt was invented by George Cayley in the late 1800’s, the seat belt appeared on planes in the early 1900’s but was later developed to a three point seat belt by Nils Bohlin. The purpose of seat belts is to restrain the forward motion that occurs during an accident, which may end up saving the person’s life or preventing serious injuries.

The seat belt was designed to restrain the person from forward motion…
