- Include a relevant diagram; e.g., for Newton’s Law problems a free-body-diagram is usually the most useful diagram.
- Start your solution from one of the fundamental equations (e.g., the equations you find on the formula sheet).
- Include all steps of formula manipulation and non-standard assumptions, to ensure that your method is clear.
- When you evaluate an equation, show the substitution of each variable’s value; just like you are required to do in lab reports.
- If you need to use a formula for the normal force, you must show how you get that formula.
- Circle or box your final answer.
- Report your final answer to 3 significant digits.
