wedges and levers
Which Simple Machine is a piece of wood, metal, or some other material having one thick end and tapering to a thin edge, that is driven between two objects or parts of an object to secure or separate them.

How do you calculate work
Work = Force × Distance.
How many Simple Machines are there
6
What Simple Machine is a simple lifting machine consisting of a rope which unwinds from a wheel on to a cylindrical drum or shaft joined to the wheel to provide mechanical advantage.
wheel and axle
Which Simple Machine is a rigid bar resting on a pivot, used to help move a heavy or firmly fixed load with one end when pressure is applied to the other.
lever
what is a dimensionless number that measures the effectiveness of a machine in transforming the power input to the device to power output.
Mechanical Efficiency
What Simple Machine is a short, slender, sharp-pointed metal pin with a raised helical thread running around it and a slotted head, used to join things together by being rotated so that it pierces wood or other material and is held tightly in place.
Screw
Which Simple Machine is also known as a ramp and is a flat supporting surface tilted at an angle, with one end higher than the other, used as an aid for raising or lowering a load.
Inclined Plane
which part of the lever is the point on which a lever rests or is supported and on which it pivots.
fulcrum
what Simple Machine requires rope, a wheel, and someone pulling
Pulley
What is the strength or energy as an attribute of physical action or movement.
Force
what is a machine that consists of more than one simple machine.
compound machine
How to calculate Mechanical Efficiency
divide the output work by the input work and multiply the result by 100 percent.
How do you calculate force
Force=Work divided by Distance
what is the ratio of the force produced by a machine to the force applied to it, used in assessing the performance of a machine.
Mechanical advantage
what is the measurement of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement.
Work
what is a scalar quantity that refers to "how much ground an object has covered" during its motion.
Distance
