(1) Newton's first law: All objects always keep moving in a straight line at a constant speed or at rest until an external force forces them to change this state.

..... can be associated with the braking system. Write down the function of braking, the effect to be achieved by braking and the braking distance. ......

An object has the property of maintaining uniform linear motion or static state, which is called inertia. Mass is a measure of the inertia of an object.

(2) Newton's second law: an object will produce acceleration after being acted on, and force is the reason for the acceleration of the object. Newton's second law points out: for an object with a certain mass, the acceleration is proportional to the acting force; Under the action of a certain force, the acceleration is inversely proportional to the mass for objects with different masses. That is F=ma.

It can be related to traction, friction coefficient between wheel and ground, the relationship between rated power and actual power of engine, etc. ...

(3) Newton's third law: the acting force and reaction force between two objects are always equal in size and opposite in direction, and act on a straight line.

..... can write the stability of the car, the relationship with wheel resistance, and the dangers of tire grinding, such as side slip. ..
