What is Newton's Second Law?
The acceleration of an object by a force is inversely proportional to the mass of the object and directly proportional to the force. Simplified, this law has two parts that we will talk about and break down in the following paragraph.

The first part of Newton's Second Law:
The law states that the larger the mass, the less amount of acceleration. If you got into a car accident and you were 100 kg, you would accelerate faster than someone who weighs 200 kg. When you are wearing a seat belt, it doesn't allow you to accelerate as much, regardless of weight. This demonstration is shown in the diagram below, using boxes:

The second part of the law and seat belts:
The law states that the more force applied to an object, the greater the acceleration. This means that the faster you are going when you crash, the more force is applied to you and the car. If you are wearing a seat belt however, it will stop you from moving forwards regardless of the amount of force applied to you. This is demonstrated in the following diagram using boxes:
