You Get What You Give
There's an Advantage
Lever and Wheel and Axle
Inclined Plane, Wedge, Screw, and Pulley
100
Work is expresses the relationship between these two variables.
What is distance and force
100
Three ways machines can make work easier are...
1. increase the input force 2. increase the input distance 3. change the direction of the force.
100
This is the found by dividing the output force by the input force.
What is actual mechanical advantage
100
If the input force is exerted on the wheel of a wheel and axle, the mechanical advantage will be ____________ than 1.
What is greater
100
An inclined plane ____________ the input force.
What is increases
200
This is the unit for work
What is joule
200
If a machine increases the input force, the input distance is _____________.
What is decreased.
200
This type of mechanical advantage is assuming there is not friction.
What is ideal mechanical advantage
200
If the input force is exerted on the axle of a wheel and axle, the mechanical advantage will be _____________ than one.
What is less

A wedge is used to ...
What is cut, split, or pierce objects
300
This is the rate at which work is done.
What is power
300
If the input distance is increased by a machine, then the input force is _____________.
What is decreased
300
What does it mean if a machine has a mechanical advantage of greater than 1.
The input force is being increased by the machine.
300

A machine that does not change force or distance could be useful by changing....
What is the direction of the force
400
What does it mean if a machine has a mechanical advantage equal to 1.
Just the direction of the force is being changed.
400
This type of lever has the fulcrum in between the input force and output force.
