with Lou gli , th Rotational dynamics study guide Part one: Conceptual concepts 1. Know what kind of force causes translational motion and what kind of force causes OP rotational motion. 2. What decides the moment of inertia of an object? 3. When opening a door, at what part of the door do you push to open it the easiest? Why? 4. If you have two different points on the same rotating disk, what qualities will they share? 5. What is inertia? What is then the moment of inertia? 6. What kind of force would apply the greatest torque? (Come up with different combinations) 7. Understand how a pulley with a couple of masses hanging on it work (what is the net torque, how it accelerates, etc.) 8. Understand conservation of momentum 9. Know the right-hand rule
