Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the pioneering mechanical computer?Vannevar Bush's Differential Analyzer (completed 1931) was a significant mechanical analog computer
2. What is the electronic component of note?Operational amplifiers (op-amps) were crucial for building versatile electronic analog computers
3. How does an analog computer solve a problem?It makes the parts of the machine represent the variables of a problem. For example, a shaft turning can show velocity, and a capacitor charging can show exponential decay. The machine does the math in real time.
4. Why were analog computers important in the past?They were very fast at solving continuous problems, like the forces in a flying airplane or the calculations needed for a naval gun. That speed made them essential for flight simulators and industrial control.

Analog Signal: A signal characterized by continuous variation in amplitude or frequency, directly representing physical quantities.
Analogon: A physical system or model constructed to behave in a manner analogous to the system or problem being studied.
Differential Equation: An equation that relates a function with its derivatives, often used to model dynamic systems in science and engineering.
Operational Amplifier (Op-Amp): A high-gain electronic voltage amplifier used in analog circuits to perform mathematical operations like integration and differentiation.
