SUMMARY
The goal of Chapter 1 has been to introduce the fundamental concepts of motion.
General Strategy
Motion Diagrams
• Help visualize motion.
• Provide a tool for finding acceleration vectors.
c
These are the average velocity and the average acceleration vectors.
Problem Solving
MODEL
Make simplifying assumptions.
VISUALIZE
Use:
•
Pictorial representation
•
Graphical representation
SOLVE
Use a
mathematical representation
to find
numerical answers.
ASSESS
Does the answer have the proper units?
Does it make sense?
