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.
