Problem 7Q

If a pendulum clock is accurate at sea level, will it gain or lose time when taken to high attitude? Why?

Step 1 of 1

The equation for pendulum motion is:

As we gain altitude the value of the constant of gravity ‘g’ decreases.

If a pendulum clock that is accurate at sea level is taken to a high altitude it will slow down. The time period is inversely proportional to the square root of ‘g’.

When ‘g’ decreases Time period ‘T’ increases.

So the clock will slow down.
