Mechanical Advantage: 200Question:Mechanical advantage is a comparison of these two forces.Answer:What is output to input?BackCalculating Mechanical Advantage: 200Question:This is the MA of the pulley system.

Answer:What is 1?Back

Miscellaneous: 200Question:Moving objects have this kind of energy.Answer:What is kinetic energy?BackWork: 400Question:The work you to a simple machine is called this.Answer:What is input or effort?BackSimple Machines: 400Question:Simple machines make work easier by doing one, two or all three of these.Answer:What is change input force, change input distance or change input direction?BackMechanical Advantage: 400Question:This simple machine always has a MA less than 1.Answer:What is a third class lever?BackCalculating Mechanical Advantage: 400Question:This is the MA of the pulley system.Answer:What is 4?Back

Miscellaneous: 400Question:A machine that uses two or more simple machines is called this.Answer:What is compound machine?BackWork: 600Question:The work a simple machine does to an object is called this.Answer:What is output or resistance?BackDaily DoubleYou can Wager All or Part of Your Points on This Question

Mechanical Advantage: 600Question:You can tell this by comparing the MA of two machines.Answer:What is which one makes work easier?Back Calculating Mechanical Advantage: 600Question:This is the MA of the lever.

Answer:What is 6?Back2 m12 mDaily DoubleYou can Wager All or Part of Your Points on This QuestionSimple Machines: 800Question:When a screwdriver is used to open a can of paint these two changes occur to the input force. Answer:What is size and direction?BackMechanical Advantage: 800Question:The MA of a first class lever can be increased by doing this.Answer:What is move the fulcrum and load closer together, or increase the length of the effort arm.BackCalculating Mechanical Advantage: 800Question:If the input force to a simple machine is 20 N and the output force is 100 N, this is the MA of the simple machine.Answer:What is 5?BackMiscellaneous: 800Question:The amount of work done on a cart to move it 100 m with a force of 550 N.Answer:What is 55,000 J?BackWork: 1000Question:To find the work done on an object, you need to know these two things.Answer:What is force and distance?BackSimple Machines: 1000Question:These changes occur to the force and distance when the longer ramp is used to move the object to the top of the ramp.

Answer:What is less force is used over a longer distance.BackMechanical Advantage: 1000Question:Wheel and axle A has a greater MA than wheel and axle B because of this.

Answer:What is the ration of the wheel to the axle is greater in A?BackCalculating Mechanical Advantage: 1000Question:This is the MA of the wheel and axle.

Answer:What is 2.5?Back10 cm25 cmMiscellaneous: 1000Question:Scissors are considered compound machines because they have these two simple machines.Answer:What is a lever and wedge?BackFinal JeopardyQuestion:Tom wants to use a ramp with a MA of 10 to roll a cart into the back of a truck. Joe wants to use a pulley system with a MA of 5 to get the cart into the back of the truck. Who will do the most work to get the cart into the back of the truck?Answer:They will do the SAME amount of work.Back
