REVIEW FOR ENERGY QUIZQuiz Date: ______
This quiz will cover information from our unit on energy. It will consist of some multiple choice, fill-in-the-blank, and short answer questions. You should review your DQs, labs, energy article, reading notes, and concepts from activitieswe’ve done. Be able to hit the following targets:
- I can define, diagram, and explain the relationship between kinetic and potential energy in different scenarios.
- I can define the different forms of potential and kinetic energy and give/explain examples of energy transformations (conversions).
- I can describe the factors that impact the amount of potential, kinetic, and total energy an object has.
1. In every energy transformation, some energy is always converted into:
A. sound energyC. chemical energy
B. thermal energyD. rotational motion energy
2. The amount of kinetic energy an object has depends directly on:
A. mass and volumeC. mass and height
B. velocity and heightD. velocity and mass
3. If the amount of kinetic energy an object has decreases, that means ______.
