Safety belts exert a force on our bodies to make the forward motion slower, thus preventing collision with the panels and reducing the risk of injury.

When the driver applies a braking force, the car slows down, but our body tends to continue in the same state of motion due to its inertia.
We tend to remain at rest with respect to the seat because of inertia, which is the tendency of an object to resist changes in its state of motion.
Another name for Newton’s first law of motion is the law of inertia, describing an object’s tendency to remain at rest or in uniform motion unless acted upon by an external force.
The tendency of undisturbed objects to stay at rest or to keep moving with the same velocity is called inertia.
Newton’s first law of motion is stated as: “An object remains in a state of rest or of uniform motion in a straight line unless compelled to change that state by an applied force.”
The three fundamental laws presented by Newton are known as Newton’s laws of motion.
Isaac Newton further studied Galileo’s ideas on force and motion.
The effect of frictional force can be minimized by using a smooth marble, a smooth plane, and providing a lubricant on top of the planes.
Galileo’s argument suggests that an unbalanced (external) force is required to change the motion of the marble, but no net force is needed to sustain its uniform motion.
