**Method 2: Configuration File**
Alibaba Cloud SDK will automatically read credential configuration from `~/.aliyun/config.json` or `~/.acs/credentials`.

**Note:** 
- For first-time use, if credentials are not detected, guide users to configure using `aliyun configure`
- Do not explicitly handle user's AK/SK credentials, rely on Alibaba Cloud default credential chain

When an object's acceleration is positive, its velocity must increase. Example 1√ Problem Situation: As shown in the figure, Figure 2. Question 1. In the previous class, we drew the velocity-time relationship graph using a dot timer. Can you find the acceleration from it? 3. The ______________ from the v-t graph determines the magnitude of acceleration. Slope. 2. The slope value of the v-t graph represents: Acceleration value. 1. Calculate the magnitude of acceleration from the v-t graph. 4. If the v-t graph line is a sloping straight line, then the object's velocity changes uniformly, its acceleration is constant, and it moves with uniformly accelerated motion. Example 2. The three lines a, b, c in Figure 1.4-6 describe the motion of three objects A, B, C. First make a preliminary judgment about which object has the greatest acceleration, then calculate their accelerations based on the data in the graph, and explain the direction of acceleration. Analysis: Slope represents acceleration, acceleration tilts to the upper right, acceleration is positive, tilts to the lower right, acceleration is negative; so a and b are accelerating, c is decelerating, the object with the greatest acceleration, i.e., the steepest slope, is a. Description of velocity change - Acceleration. 1. Physical meaning: Describes how fast an object's velocity changes. 2. Definition: The ratio of the change in velocity to the time taken for that change. 3. Definition formula: 4. Vector nature: 5. Acceleration and velocity. Acceleration and velocity change. 6. Viewing acceleration from v-t graph: The slope value of the graph represents the acceleration value. Direction of a, accelerating motion. Direction of a, decelerating motion. Same as v0 direction.",

Learning objectives: Task 1: Understand the physical meaning of acceleration, be able to state the definition formula and unit of acceleration. Task 2: Be able to describe the relationship between the direction of acceleration and the direction of velocity. Task 3: Be able to distinguish between velocity, velocity change, and velocity change rate (acceleration). Understand variable speed motion. Task 4: Be able to determine acceleration from v-t graphs. 1. What is the reason for the distance between each car's final speed of 100 km/h? 2. What is the difference in their acceleration process motion? 3. Can you accurately compare the performance of these cars? Different rates of velocity change || Initial velocity (km/h) | Final velocity (km/h) | Time taken (s) | | A car start | 0 | 100 | 8.02 | | B car start | 0 | 100 | 9.53 | | C car start | 0 | 100 | 5.43 | | D car start | 0 | 100 | 4.47 | Table 1: Racing car 0~100 km/h sprint record. 4. With precise data, how to accurately compare the acceleration rate of cars? 5. Which car has the fastest velocity change? 6. Can you use other ways to compare the rate of velocity change?
