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