Final answer:
The 4 steps involved in evaluating e1; e2 are examining the situation, determining the forces involved, analyzing the forces and potential energy, and applying physical principles to solve the problem.
Step-by-step explanation:
The 4 steps involved in the evaluation (dynamic semantics) of e1; e2 are:
- Examine the situation to determine which physical principles are involved
- Examine all the forces involved and determine whether you know or are given the potential energy from the work done by the forces
- Use step 3 or step 4 to analyze the forces and determine the potential energy
- Apply the physical principles to solve the problem and evaluate the result
