Which of newtons laws explains the following scenario: A car suddenly stops and the luggage on top of the car flies forwards off the car.
A. Newtons 1st law
B. Newtons 2nd law
C. Newtons 3rd law
D. Law of universal gravitation
A. Newton's 1st law
This law, also known as the law of inertia, states that an object at rest stays at rest and an object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. In the scenario you described, when the car suddenly stops, the luggage on top of the car has a tendency to remain in motion due to its inertia. Since there is no unbalanced force to keep the luggage moving with the car (assuming the luggage was not properly secured), it continues moving forward and can fly off the car.
