<span>Inertia is defined as the tendency to remain unchanged
unless an unequal outside force is acting on it. In physics, it is the property
of matter to continue at rest or in motion unless that state is acted or
changed by an external force. When the car moves, the person sitting on it has
the same velocity with that car. During a collision, there will be an abrupt
change in the car’s velocity. The person without a seatbelt will be thrown away
from his seat with the same velocity as the car towards the direction at which
the car is heading. In this case, that person will be thrown away at the front
of the car. This will be a dangerous scenario as he might sustain a fatal
injury after the impact.</span>
