How does inertia affect a person who is not wearing a seatbelt during a collision?

A person who is not wearing a seatbelt during a collision will be thrown forward because it maintains forward motion

In Newton's law, it is stated that if the resultant force acting on an object of magnitude is zero,  it can be formulated :

then the object tends to defend itself from its state. So for objects in a state of movement, objects tend to move forever. Likewise, for objects in a state of rest, they tend to remain forever. The tendency of objects like this is called inertia

The size of inertia is proportional to mass, the greater the mass of the object, the greater the inertia of the object.

In objects with mass m that move translatively, the object will maintain its linear velocity

When we are in a vehicle that moves forward, then we will still maintain a state of forwarding motion. If our vehicle stops suddenly, then we keep moving forward so we will be pushed forward. From this point, the use of a safety belt serves to hold back our movements so that there are no fatal accidents or collisions.
