Define problem

明确分析物理量, 化简题目给的方程式 \(f(x) = kx + b\)

1. Dependent variable \(f(x)\):
2. Independent variable \(x\):
3. Control varable(s):

• 画草图

Data collection

1. 列举所有变量的测量方法
2. 重复测量保证精确

Method of analysis

1. "Plot the graph of (dependent variable) against (independent variable)."
2. "If the given function is true:" 分析是否过原点, 斜率和y轴交点的意义
   • The gradient of the best-ft line is _____ ,thus \(Gradient\) = _____.
   • The \(y_{intercept}\) of the best-ft line is _____ ,thus \(y_{intercept}\) = _____.
3. Caculation:
   (tested variable) = \(Gradient \times y_{intercept}...\)

(Addtions)

1. 写之前没写到的点 测量/实验方法
2. Safty precautions:

Situations	Precautions
High voltage/current	Plastic golves
Object falling	Sand boxes
Light object affected
Circuit
Liquid
