Which of the following physical laws explains why a passenger sitting in a moving bus falls forward when the driver suddenly applies brakes?

💡 Solution & Explanation

Newton First Law of Motion, also known as the law of inertia, explains that a body maintains its state of rest or uniform motion unless compelled by an external force. When a moving bus applies brakes, the lower part of the passenger body slows down with the vehicle, but the upper part continues moving forward due to inertia. This principle forms the foundational basis for classical mechanics in physics.
