), always remember the order matters. Use the determinant method to avoid simple sign errors. 3. Dynamics: Kinematics vs. Kinetics Students often confuse how things move with why they move.
or Work-Energy theorems, you are dealing with the causes of motion. 4. The "Work-Energy" Shortcut Before you dive into a massive calculation, ask yourself:
Half of all failed mechanics problems are due to forgetting to convert millimeters to meters or pounds-mass to slugs.
