This is Work, Power, Machines & Energy JEOPARDY It’s Time To Work Power Simple Machines Forms of Energy Levers Assorted 100 100 100 100 100 100 200 200 200 200 200 200 300 300 300 300 300 300 400 400 400 400 400 400 500 500 500 500 500 500 The work done on an object is this type of quantity because technically it has magnitude but not a specific direction. A 100 What is a scalar quantity? A 100 It acts on an object to displace it during work. A 200 What is a force? A 200 When negative work is done, the force acts on an object in the opposite direction to this. A 300 What is the object’s displacement? A 300 This force does negative work on a filled cardboard box as you try to push it across the floor. A 400 What is friction? A 400 This component of the force on the object actually does the work. A 500 The horizontal component of the force. A 500 Power is the rate at which this is done. B 100 What is work? B 100 The unit of power. B 200 What is a watt? B 200 A watt is equivalent to this how many of these per second. B 300 What is a Joule? B 300 A motor’s power is calculated as the product of its velocity and the amount of this it produces. B 400 What is force? B 400 This scientist/inventor of a steam engine, tested a strong horse to determine its power was 550 foot-pounds per second. B 500 Who was James Watt? B 500 A simple machine is able to do work in this number of movements. C 100 What is one? C 100 A ramp is an example of this kind of simple machine. C 200 What is an inclined plane? C 200 This simple machine is produced by wrapping a long inclined place around a shaft. C 300 What is a screw? C 300 DAILY Place A Wager DOUBLE C 400 Simple machines can make work easier by multiplying the effort force and by changing this. C 400 What is the direction of the force? C 400 With regards to the amount of work done, machines can never do this. C 500 What is reduce the amount? C 500 Energy may be defined as the ability to do this. D 100 What is work? D 100 Energy is equivalent to this which occurs when a force is applied to an object to displace it. D 200 What is work? D 200 The scientific law that states Energy cannot be created or destroyed in a closed system. D 300 The law of conservation of energy D 300 This type of energy source cannot be replaced within a lifetime. D 400 What is nonrenewable? D 400 These are two examples of nonmechanical energy. D 500 What are: Chemical, Radiant, Electrical etc. D 500 A lever is this type of machine. E 100 What is Simple? E 100 A support on which a lever can pivot. E 200 What is a fulcrum? E 200 A pry bar is an example of this class of lever. E 300 What is a first-class lever? E 300 A broom is an example of this class of lever E 400 What is a third-class lever? E 400 These are the two names used to describe the lever arms on either side of a first class lever’s fulcrum. E 500 What are the effort and resistance arms? E 500 The energy of motion. F 100 What is kinetic energy? F 100 Type of potential energy related to an object’s height. F 200 What is gravitational potential energy? F 200 This aspect of a “real” machine is related to the number of times a machine multiples the effort force. F 300 What is the Mechanical Advantage (MA) of that machine? F 300 This is always missing from the operation of an “Ideal Machine.” F 400 What is Friction? F 400 The class of lever in which the resistance is placed between the fulcrum and the effort force. F 500 What is a secondclass lever? F 500 The Final Jeopardy Category is: Simple Machines Please record your wager. Click on screen to begin This simple machine is most like a first class lever.
