## Lesson 1 Check 1. Explain how energy and motion are related? * Energy is needed for motion. 2. Apply Concepts Give an example in which energy produces a force that causes motion. * It takes energy to apply a force on a pencil for it to work. 4. Calculate what force was applied to an object if 35 J of work was done and the object moved 7 m? Show your work. * Force = Work/ distance * Force = 35 / 7 * Force = 5N 5. Evaluate Data A student did 24 J of work on a chair. She applied a force of 12 N and moved the chair 2 m. What else do you need to know to determine the amount of power used? * Time 6. Cause and Effect | Cause | Effect | | :------------------------------------ | :------ | | Energy transferred over time | Power | | Force applied to an object to change its position | Motion | | Force moving an object over a distance | Work | ## Test CHECK-IN In this lesson, you learned about basics of energy and how force and motion relate to it. You also learned about how these concepts relate to how work is done. * How do the concepts of energy, force and motion relate to the machine you will be designing? What factors will you have to consider in your design? ## INTERACTIVITY * **Applying Energy** Go online to learn about how energy, force, and motion relate to machines. Then, develop the design for your machine.
