The output speed of a gear linked to another gear, with a speed of 100 rpm, via a chain.
What is 100 rpm?
100
This simple machine, consisting of a sloped surface, allows heavy objects to be moved with less effort.

The type of force that describes torque.
What is a rotational or twisting force?
300
This simple machine, consisting of a rigid bar pivoted at a point, provides mechanical advantage by reducing the force needed to move an object.
What is a lever?
300
In a chain drive system, the gear ratio is also determined by the ratio of the diameters or this physical attribute of the gears.
What is the number of teeth?
300
This common mechanism, consisting of a wheel with a grooved edge and a rope or chain, is used to lift or lower loads.
What is a pulley?
300
The correlation between an object's mass, acceleration, and force acted upon it.
What is Newton's Second Law? (F = ma)
300
The calculation for speed.
What is distance over time? (also m/s or d/t)
400
For gears, the ideal mechanical advantage is determined by comparing this ratio between the driver and driven gears.
What is the gear ratio?
400
If a driving gear has 20 teeth and the driven gear has 40 teeth, the gear ratio is this.
What is 2:1?
400
This type of mechanism uses a pair of opposing slanted surfaces to convert linear motion into rotary motion.

400
This is the term for the acceleration experienced by all objects in free fall near the surface of the Earth.
What is gravitational acceleration (or 9.8 m/s)
400
This term refers to how quickly an object rotates, typically measured in revolutions per minute (RPM).
