Work Practice Problems Worksheet #1 ANSWER KEY 1) Amy uses 20N of force to push a lawn mower 10 meters. How much work does she do? Work = Force X Distance Work = 20N X 10m Work = 200 J 2) How much work does an elephant do while moving a circus wagon 20 meters with a pulling force of 200N? Work = Force X Distance Work = 200N X 20m Work = 4000 J

Force, Distance, and Work 1. What 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.
1. _____ is done when an object moves through a distance because of a _____ acting upon the object. 2. When calculating work, you should use the formula: work = force X _____. 3. The SI unit for work is the _____. It is represented by the letter _____. C. Work Problems: 4.
Work = Force x Distance. Work is the product of the force applied to an object and the distance the object moves. The unit of work is the joule (J).
If a small machine does 2,500 joules of work on an object to move it a distance of 100 meters in 10 seconds, what is the force needed to do the work? What is the power of the machine doing the work?
Force-Distance graphs If the force is non-uniform then the formula W = F × d does not apply. Instead, we present the information as a force-distance graph and calculate the area beneath the graph to find the work done by the force. Recall the other “area under a graph”, which is the force-time graph that gives the impulse of a force.
