Describe what the code to the left
does:
Two people working together to create a computer program. One person, called the driver, writes the code and explains the logic, while the other person, called the navigator, reviews it and gives feedback.
An ordered set of instructions that are used to carry out a task.
An action or occurrence that happens during runtime that will trigger a response or behavior by the software. Examples of events include user-initiated events, such as clicking a button, or external events, such as the device receiving an SMS text message.
A block of code that is triggered when a certain event happens.

For this gear train, does the output speed increase, decrease, or stay the same?
For each of the following gear ratios (based on the number of teeth), determine whether the output speed increases, decreases, or stays the same.
48/48
60/48
24/72

36/12
Increase
Decrease
Stays the same
Why do designers and engineers care about gear ratios?
