Detailed explanation-1: -As a more familiar example of inertia, think about riding in a car. You and the car have inertia. If the car comes to a sudden stop, your body tends to keep moving forward. When the car starts moving again, your body tends to stay at rest.
Detailed explanation-2: -In reality, we are experiencing inertia: our body (already in motion, moving forward with the car) will remain in motion until acted upon by an unbalanced force. So we are not actually being thrown forward–we are moving forward as we always have.
Detailed explanation-3: -As per Newton’s first law of motion, when a car abruptly stops or crashes, Due to inertia of motion, a person sitting in a moving car may be pushed forward when the car stops abruptly, potentially causing damage. To prevent the above accident, seat belt must be used while driving car.
