The correct answer is inertia. Inertia is the tendency of an object to resist changes in its motion. In this scenario, when you hit the brakes, your body wants to keep moving forward due to its inertia, but the seatbelt stops your body from doing so.
The correct answer is inertia. Inertia is the tendency of an object to resist changes in its state of motion. When you hit the brakes while driving, your body wants to keep moving forward due to its inertia, but the seatbelt stops you and brings you back into equilibrium. To explain this, the concept of Newton's first law of motion is helpful. According to this law, 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 external force. When you hit the brakes, the external force is applied to your body, causing it to move forward, against its initial motion. However, the seatbelt applies an opposing force that brings your body to a stop, preventing it from continuing to move forward. Therefore, your body moving forward before the seatbelt stops you is an example of inertia.
