What is the importance of newton's laws of motion to road safety?

Answer 1

This is because this law deals with inertia stating that the property of matter that causes a body to resist changes in its state of motion. So if a person is driving and suddenly presses on the break, the top half of your body is still moving yet the bottom half has stopped causing a jerk reaction where you suddenly move back into your seat. So it is important for you to wear your seat belt so something like this would not happen.

Answer 2

1st law: an object in motion stays in motion, and an object at rest stays at rest unless acted upon by an outside force.

Your car will continue moving even after you take your foot off the gas because of inertia. You need to wait until the friction of the tires on the road slowly stops the car, or you have to press the breaks to stop the car safely.

When the car comes to sudden stop, you will keep moving forward unless acted upon by an outside force, such as a seatbelt or an airbag.

3rd law: for every action, there is an equal and opposite reaction.

This directly applies to car crashes. If your car crashes into a telephone pole, the telephone pole is also crashing against your car. Both the car and the telephone pole are exerting forces upon each other, so the car will probably be dented, as will the telephone pole.

Answer 3

Slowing (negative acceleration) to stop, or slow to keep out of an accident. Forces to change direction, particularly on slick roads.
