Think about how Newton’s First Law of Motion applies to you. Imagine that you are riding in a car when the driver abruptly steps on the brake. Use Newton’s First Law of Motion and any applicable vocabulary terms from above to explain why your body tends to move forward when this happens. written as a 9th grader
Newton's First Law of Motion states that an object in motion will stay in motion with the same speed and direction unless acted upon by an external force. This law can explain why my body tends to move forward when the driver abruptly steps on the brake in a car.
When the car is moving forward, my body is also moving at the same speed and direction. According to Newton's First Law, my body wants to continue moving forward because of its inertia. Inertia is the tendency of an object to resist changing its state of motion. So, when the driver suddenly applies the brakes, it acts as an external force that tries to bring the car to a stop.
However, due to my body's inertia, it initially wants to resist this change in motion and continue moving forward. This causes my body to lurch forward. This forward motion is because there is not enough friction between my body and the car seat to stop me instantly when the brakes are applied. As a result, I experience a brief period of time where I continue moving in the car's original direction until the car comes to a complete stop, or until additional forces counteract my forward motion.
This phenomenon can be better understood with the help of Newton's First Law and terms like inertia and external force. In summary, when the driver suddenly brakes, my body tends to move forward because of its inertia, which resists any change in its state of motion.
