<h3>Further explanation </h3>In Newton's law, it is stated that if the resultant force acts on an object of magnitude is zero, it can be formulated:
<h3>∑F = 0 </h3>This value is for stationary objects or objects that move in a straight line
So if the resultant force on an object is zero, the object that was initially stationary will continue to remain stationary, and the object that was initially moving will continue to move at a constant speed
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 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 injuries or collisions.
