How Did the First Clocks Measure Time Before Electricity?

Imagine a big, heavy ball swinging back and forth like a pendulum, that’s how the first clocks measured time! People used something called a pendulum clock, which ticked steadily without needing electricity. The more precise they made it, the better their timekeeping became.

At the heart of these clocks was a simple idea: a pendulum swings at an even rate if it’s not too long or short. Every swing counted as one second, and gears turned to mark minutes and hours. It was like counting with a rhythm!

These clocks were big, but they were so accurate that people could tell the time all day, no batteries needed!
