Meaning and Definition
A clock, typically a pendulum clock, whose timekeeping mechanism is primarily regulated by the force of gravity acting on a weight.
In broader historical or conceptual contexts, any timekeeping device that utilizes the constant force of gravity as its driving or regulating principle, distinct from spring-driven or electronic mechanisms.

Common Mistakes When Using “gravity clock”
- Using 'gravity clock' to refer to any old-looking clock, regardless of its mechanism. Confusing it with 'astronomical clock' or 'water clock'. Incorrectly using it as a verb or adjective.
FAQ
Frequently Asked Questions
Typically, yes. Most traditional grandfather clocks (longcase clocks) are weight-driven and therefore qualify as gravity clocks, but the term 'grandfather clock' refers to the case style, not the mechanism.
Before modern alloys, gravity provided a more constant driving force than a mainspring, which loses torque as it unwinds. This contributed to better timekeeping accuracy over long periods.
No. They are purely mechanical. The energy comes from the potential energy stored in a raised weight, which is converted to kinetic energy as it falls.
It depends on the length of the weight's fall. Some need winding daily, others weekly, or even longer. Winding involves pulling the weight back up to the top of its travel.
