Question

Identify, in order, the six steps basic to both PERT and CPM.

Answer 1

The six basic problem-solving steps for physics are: examine the situation, identify the knowns and unknowns, find the appropriate equations, substitute values, solve for the unknowns, and check the answer for reasonability.

Step-by-step explanation:

1. Step 1: Examine the situation to determine which physical principles are involved.
2. Step 2: Make a list of what is given or can be inferred from the problem (identify the knowns).
3. Step 3: Identify exactly what needs to be determined in the problem (identify the unknowns).
4. Step 4: Find an equation or set of equations that can help you solve the problem.
5. Step 5: Substitute the knowns along with their units into the appropriate equation, and obtain numerical solutions complete with units.
6. Step 6: Check the answer to see if it is reasonable: Does it make sense?
