FORCE, DISTANCE, AND WORK Force, Distance, and Work 500.0 2.0 4.0 6.0 8.0 10.0 Distance (m) (Note: Force and distance are in the same direction.) SIMPLE MACHINES 1. List the simple machines shown from left to right, starting with the top row. 2. What is Fe? 3. What is Fr? 4. For which of the machines shown is output work greater than input work? Explain your answer. 5. What are the directions of FE and Fr for the wheel and axle? 6. After the effort force is exerted on the wedge, describe the direction of the machine's load. 7. What equation would you use to determine the IMA of each machine? 8. If the mechanical advantage of the wedge is greater than one, what can you tell about the force exerted on the machine and the force exerted by the machine? FORCE, DISTANCE, AND WORK 1. What magnitude of force acts on the object when it has been moved 4.0 m? 2. How far has the object been moved when the force on it is 200.0 N? 3. Explain the shape of the line on the graph. 4. Which formula is used to calculate work when a constant force is exerted on an object? 5. How much work is done in moving the object 4.0 m from the source to 6,0 m from the source? 6. Look at the information on the graph about the object as it is moved 6.0 m from its source to 10.0 m from its source. How much work is done in moving the object? 7. How much work is done in moving the object the 10.0-m distance shown on the graph?
