Mathematical skills of the first day of the moving point problem
The math skills of moving questions in Grade One are as follows:

1, establish the coordinate system.

The moving point problem is transformed into a geometric problem, and the motion law of the moving point is described by establishing a coordinate system.

2, determine the variables

Find the variables of the moving point, such as time, speed, distance, etc.

3. Establish an equation

According to the requirements of the topic, the equation about the motion law of moving point is established.

4. Classified discussion

According to the movement of the moving point, the classification discussion is carried out, and the solution methods in various situations are determined.

Step 5 draw a picture

According to the requirements of the topic, draw a figure to show the motion law of the moving point intuitively.

6. Solve the result

According to the established equation and the drawn graph, the motion law and results of the moving point are solved.
