Question
Which of Newton's laws explains why one should always wear a seatbelt?A Newton's first lawB Newton's second lawC Newton's third lawD Newton's fourth law
Solution
The answer is A, Newton's first law. This law, also known as the Law of Inertia, states that an object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
In the context of wearing a seatbelt, if a car suddenly stops or crashes, the seatbelt provides the unbalanced force that stops the passenger from continuing to move forward at the same speed and direction, which could result in injury or death.
