Denser, heavier air.
It's faster at sea level and slower at the top of a mountain.
The time period of oscillation of the pendulum is inversely proportional to the square root of the value of acceleration due to gravity (g) at that place. g is low at heights above the sea level. So T increases. Period increases. So frequency decreases. Hence the slow movenment.
pendulum's slow down during summers because the pendulum expands and it moves faster during winters because the pendulum contracts
As the force of gravity increases the period would decrease. So shortest period on the sun (if you can keep it intact), then sea level, then mountain top and then moon.
..weigh less and the pendulum will swing at a slower rate. It might become more valuable (high mountain areas have less access to fine clocks than many sea level communities).
why pendulum clocks dont work at sea
it will lose time. it slows as you change level....change of gravity
The pendulum will lose energy, due to friction.
Gravitational instruments are calibrated at sea level at 45 degrees north because the gravitational pull of the earth varies in various places. A pendulum will run faster or slower according to the gravitational pull.
If the length of a pendulum is increased, the pendulum will take longer to complete a swing, and the clock will slow down. Shortening the pendulum will speed up the clock.
Yes. If you take a pendulum and set it swinging it's friction of the pendulum against the air, and internal friction in the line that will eventually slow the pendulum down.
Air resistance.
