1. Which of the following are vectors: work, potential energy, kinetic energy, momentum? Explain. 2. State the principle of the conservation of momentum. What conditions are needed for this principle to hold for a given interaction? 3. If you throw a heavy rock forwards from your hands while standing on a skateboard, you roll backwards. Would you roll backwards if you didn't actually throw the rock but went through the motions of doing so? Explain. 4. Two pucks with equal mass and equal speed approach each other from opposite directions. What is the total momentum before the collision? What is the total momentum after the collision? *See the text for a description of momentum and energy. Be sure you can answer all the prelab questions or similar questions.
