If i had a pendulum clock a meter stick and a stopwatch could I find the acceleration of gravity on the moon?

The time it takes a pendulum to complete a full swing is given by the formula:
T = 2 pi sqrt(L/g)
where L is the length of the pendulum, and g is acceleration due to gravity. With a little algebra we can rearrange this to get:
g = (2 pi / T)^2 L
So measure the length of your pendulum to get L, then measure how long it takes for a complete swing, plug it into the formula, and there's your acceleration due to gravity. You can try it here on Earth and see what you get.

Can the pendulum clock be used to measure time in a spaceship orbiting around the earth?
No, there is no gravity gradient. Though it could be if it was somehow mounted in a centrifuge.
Who invented the pendulum clock?
Christan Huygens invented the pendulum clock in 1659. Christan huygens is a Dutch Scientist.The invention of the pendulum clock is credited to Christian Huygens who developed working versions in the mid 1650's AD. A couple decades earlier, Galileo came up with designs for a pendulum clock, though it was not completed.
Who made the pendulum clock?
Christiaan Huygens
Does gravity change at high altitude?
Yes. When the distance between the object's centers of mass increases, the force of gravity weakens (this can be measured experimentally on Earth at low elevations and high elevations with a sensitive pendulum and an accurate clock).
Why didn't navigators on sailing ships just use a pendulum clock to keep time?
Pendulum clocks have a pendulum that moves, so on a moving ship the clock would not work right. The ships movement would throw off the clock telling the right time.
Did anyone succeed in generating power from gravity just gravity?
Every clock run by weights and a pendulum uses gravity power.
What Causes of pendulum to swing?
i think that it might be gravity are we talking bout a clock? or someting on a string?
How Does the angle affect the simple pendulum?
By dampening. This can be done by changing the length of the pendulum The period is 2*pi*square root of (L/g), where L is the length of the pendulum and g the acceleration due to gravity. A pendulum clock can be made faster by turning the adjustment screw on the bottom of the bob inward, making the pendulum slightly shorter.
Relationship between period of pendulum and length?
The longer a pendulum is, the more time it takes a pendulum takes to complete a period of time. If a clock is regulated by a pendulum and it runs fast, you can make it run slower by making the pendulum longer. Likewise, if the clock runs slow, you can make your clock run faster by making the pendulum shorter. (What a pendulum actually does is measure the ratio between time and gravity at a particular location, but that is beyond the scope of this answer.)
What effect would the temperature have on the time kept by a pendulum clock if the pendulum rod increase in length with an increase in temperature?
The angular frequency w of a pendulum under the force of gravity isw = Sqrt(g/L)where g is the gravitational acceleration at the Earth's surface. Most materials tend to expand when their temperature is increased. If L increases, the quantity g/Ldecreases, and therefore w decreases. This will have the effect of slowing down the pendulum rod and therefore slowing down the clock.
A pendulum clock at high altitudes runs?
Slower (lower frequency, really), due to the reduced gravity.
Who invented to pendulum clock?
Huygens invented the pendulum clock, and don't confuse Huygens with Einstein, because Einstein did not invent the pendulum clock.
How do you adjust a pendulum on a clock?
The pendulum of a clock is usually constructed with some sort of clamp or sliding catchthat permits sliding the weight up and down the stick, raising or lowering its center of massand thus changing its effective length.-- If the clock is running too fast, and has to be turned back a few minutes every now and then,make the pendulum slightly longer, by sliding the weight down a bit on the stick. This makesthe pendulum swing slightly slower.-- If the clock is running too slow, and has to be turned a few minutes ahead to catch up everynow and then, make the pendulum slightly shorter, by sliding the weight up a bit on the stick.This makes the pendulum swing slightly faster.
Why wouldn't a pendulum clock wouldn't work properly on the moon?
Because there is very little gravity there and so everything is lighter, meaning the pendulum would not swing the way it does on Earth.
Who is the inventor of the stopwatch?
The inventor of the stopwatch was Samuel Watson. He invented the stopwatch in 1695. Samuel was a clock and watch maker.
When was the pendulum clock invented?
1656Christiaan Huygens invented the pendulum clock and was the most accurate clock into the 1930s.
How would the time period of a simple pendulum clock be affected if it were on the moon instead of the earth?
The time period of a pendulum would increases it the pendulum were on the moon instead of the earth. The period of a simple pendulum is equal to 2*pi*√(L/g), where g is acceleration due to gravity. As gravity decreases, g decreases. Since the value of g would be smaller on the moon, the period of the pendulum would increase. The value of g on Earth is 9.8 m/s2, whereas the value of g on the moon is 1.624 m/s2. This makes the period of a pendulum on the moon about 2.47 times longer than the period would be on Earth.
