100

A simple machine that consists of an inclined plane wrapped around a cylinder or cone is this.
What is a screw?

100

Efficiency and a comparison of mechanical advantage and ideal mechanical advantage gives you an idea of this.
What is how much energy is lost due to friction in a machine?

100

A simple machine consisting of a bar that rotates around a fixed point called a fulcrum is this.
What is a lever?

100

The number of times a machine multiplies input force is known as this.
What is mechanical advantage?

100

This is the rate at which work is done.
What is power?

200

A type of lever there the fulcrum is located on the far side of the input force area, has an ideal mechanical advantage less than 1, and does not result in a change in the direction of force is this.
What is a third class lever?

200

This is the SI unit for power.
What is Watt?

200

A simple machine that consists of two connected rings or cylinders, one inside the other, which both turn in the same direction around a single center point is this.
What is a wheel and axle?

200

The SI unit for work is this.
What is Joule?

200

When the force is applied to the wheel of a wheel and axle machine, the axle has this amount of output force relative to the input force.
What is more?

300

A type of lever where the fulcrum is between the input and output force areas, and results in a change in the direction of the force is this.
What is a first class lever?

300

Compound machines tend to have a lower efficiency than simple machines due to this.
What is friction?

300

This is a device that makes work easier by changing a force.
What is a machine?

300

This value associated with a compound machine is the product of all the simple machines incorporated into the compound machine.
What is mechanical advantage?

300

When the force is applied to the axle of a wheel and axle machine, the wheel has this amount of output force relative to the input force.
What is less?

400

This is the use of force to move an object.
What is work?

400

A compound pulley is made up of these.
What are fixed and movable pulleys?

400

A machine made of more than one simple machine is this.
What is a compound machine?

400

A simple machine that consists of two inclined plane and only is functional when it moves is this.
What is a wedge?

500

A simple machine that consists of a rope and grooved wheel is known as this.
What is a pulley?

500

This represents the multiplication of input force that would be achieved in the absence of friction.
What is ideal mechanical advantage?

500

A simple machine consisting of a sloped surface that connects lower and higher elevations is this.
What is an inclined plane?

500

The percent of input work that becomes output work is known as this.
What is efficiency?

500
