Work: 200 Question: To calculate work, you need to know these two things. Answer: What is force and distance?

Work: 400 Question: The work you to a simple machine is called this. Answer: What is input or effort?

Work: 600 Question: The work a simple machine does to an object is called this. Answer: What is output or resistance?

Work: 800 Question: For work to occur on an object, the force must do this. Answer: What is be in the same direction as the motion?

Work: 1000 Question: To find the work done on an object, you need to know these two things. Answer: What is force and distance?

Simple Machines: 200 Question: This type of pulley only changes the direction of the force acting on an object. Answer: What is a single fixed pulley?

Simple Machines: 400 Question: 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?

Simple Machines: 600 Question: 3 rd class levers, like a broom, make work easier by doing this. Answer: What is multiples the input distance?

Simple Machines: 800 Question: 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?

Simple Machines: 1000 Question: 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.

Mechanical Advantage: 200 Question: Mechanical advantage is a comparison of these two forces. Answer: What is output to input?

Mechanical Advantage: 400 Question: This simple machine always has a MA less than 1. Answer: What is a third class lever?

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

Mechanical Advantage: 800 Question: 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.

Mechanical Advantage: 1000 Question: 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?

Calculating Mechanical Advantage: 200 Question: This is the MA of the pulley system. Answer: What is 1?

Calculating Mechanical Advantage: 400 Question: This is the MA of the pulley system. Answer: What is 4?

Calculating Mechanical Advantage: 600 Question: This is the MA of the lever. Answer: What is 6? 2 m 12 m

Calculating Mechanical Advantage: 800 Question: 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?

Calculating Mechanical Advantage: 1000 Question: This is the MA of the wheel and axle. Answer: What is 2.5? 10 cm 25 cm

Miscellaneous: 200 Question: Moving objects have this kind of energy. Answer: What is kinetic energy?

Miscellaneous: 400 Question: A machine that uses two or more simple machines is called this. Answer: What is compound machine?

Miscellaneous: 600 Question: The joints in your body act as this part of a lever. Answer: What is fulcrum.

Miscellaneous: 800 Question: 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?

Miscellaneous: 1000 Question: Scissors are considered compound machines because they have these two simple machines. Answer: What is a lever and wedge?

Final Jeopardy Question: 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. Place your wager. Category: Work
