Clock homework help

Electrical clocks are the most common type of clock used today. Atomic clocks measure time using the waves of energy given off by atoms—the tiny bits of matter that make up the universe. Atomic clocks normally have digital displays. Because atomic clocks are the most accurate type of clock, scientists use them in their work.

Mechanical clocks get their power from moving weights or springs. These parts are attached to gears, or toothed wheels. The gears are attached to the hands of the clock. As the gears move they move the hands. Another device attached to the gears keeps them moving at a regular pace. Mechanical clocks must be wound up to work.

Atomic clocks measure time using the waves of energy given off by atoms—the tiny bits of matter that make up the universe. Atomic clocks normally have digital displays.

How Clocks Work. There are three main types of clocks: mechanical, electrical, and atomic. All three have the same basic parts. They must have a source of power, a device to keep the parts moving at regular intervals, and a way to display the time. Mechanical clocks get their power from moving weights or springs.
