How to find the length of a pendulum?
The length of a pendulum can be found by measuring the distance from the point of suspension to the center of mass of the pendulum bob. This distance is known as the length of the pendulum.
Why does the period length of a pendulum increase when its amplitude is increased?
If you'll do some careful measurements, you'll find that it doesn't happen that way.The period of a pendulum depends on its length, but not on how far you pull it to start it swinging.
What is the period of a simple pendulum 80 cm long a on earth and b when it is in a freely falling elevator?
a) The period of a simple pendulum on Earth depends on the acceleration due to gravity, which is approximately 9.81 m/s^2. Using the formula for the period of a pendulum, T = 2pisqrt(L/g), where L is the length of the pendulum (80 cm = 0.8 m), we find T = 2pisqrt(0.8/9.81) ≈ 1.79 seconds. b) In a freely falling elevator, the acceleration due to gravity acts on both the elevator and the pendulum, so the period of the pendulum remains the same as on Earth, assuming no air resistance or other external factors.
Pendulum has a gravitational potential energy of 224 J when it is at its highest point At the lowest point in its swing it has a velocity of 4 ms What is the mass of the pendulum?
To find the mass of the pendulum, we need more information such as the height of the highest point and the length of the pendulum. With the given information, we cannot determine the mass of the pendulum. The mass of the pendulum depends on various factors including its potential energy, velocity, and dimensions.
What variables affect how fast a pendulum swings?
The simple answer (what most high school teachers, for example, would say)is that the period (length of time for a swing) only depends on the length of thependulum. This is a pretty good approximation for a well-made pendulum.============================When you sit down to work out the period of a pendulum on paper, you draw a mass,hanging in gravity, from the end of a string that has no weight, with no air around it.When you turn the crank, you discover that the period of the pendulum ... the timeit takes for one complete back-and-forth swing ... depends only on the length ofthe string and the local acceleration of gravity, and that the pendulum never stops.When you build the real thing, you discover that your original analysis is a little bit 'off'.Your physical pendulum always stops after a while, and while it's still going, theperiod is slightly different from what you calculated. So you begin to do researchexperiments to figure out why.Eventually, you figure out that the weight of the string makes the effective lengthof the pendulum different from the actual length of the string, and that the pendulumloses energy and stops because it has to plow through air.What you do to reduce these influences:-- You use the lightest, strongest string you can find, and the heaviest mass thatthe string can hold, so that the mass at the end is huge compared to the mass ofthe string.-- You operate the whole pendulum in an evacuated tube ... with all the air pumped out.When you do that, you have a pendulum that's good enough, and close enoughto the theoretical calculation, that you can use it to measure the acceleration ofgravity in different places.
A simple pendulum of length 20cm took 120 seconds to complete 40 oscillation find its time period?
The period of a simple pendulum of length 20cm took 120 seconds to complete 40 oscillation is 0.9.

How do you find time period of pendulum?
T=2π√(L/g)where L is the length of the pendulum and g is the local acceleration of gravity.

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.
What is the period of a simple pendulum is its frequency is 20 Hz?
The period of a simple pendulum is the time it takes for one full oscillation (swing) back and forth. To find the period, you can use the formula: Period = 1 / Frequency. So, if the frequency is 20 Hz, the period would be 1/20 = 0.05 seconds.
What is the significance of 15cm 17828 on the movement of a chiming clock?
I have this on my 8 day mantel clock, Its the only marking that I can find. I have looked up this information elsewhere. 15 cm is the pendulum length, and 17828 is actually 178.28 beats per minute of the pendulum
Find the Lagrangian of simple pendulum?
The generalized coordinate for the pendulum is the angle of the arm off vertical, theta. Theta is 0 when the pendulum arm is down and pi when the arm is up. M = mass of pendulum L = length of pendulum arm g = acceleration of gravity \theta = angle of pendulum arm off vertical \dot{\theta} = time derivative of \theta What are the kinetic and potential energies? Kinetic energy: T = (1/2)*M*(L*\dot{\theta})^2 Potential energy: V' = MLg(1-cos(\theta)) V = -MLg*cos(\theta) --note: we can shift the potential by any constant, so lets choose to drop the MLg The Lagrangian is L=T-V: L = (1/2)ML^2\dot{\theta}^2 + MLg*cos(\theta)
A pendulum of the length L is suspended from the ceiling of an elevetor. When the elevator is at rest the period of pendulum is T. What is the period of the pendulum if the elevator is freely falling?
A lift in free fall is the same as a lift with no gravity (e.g. in space), i.e. accelleration due to gravity, g = 0 ms^-2. Now your intuition should tell you what's going to happen but even if it doesn't you can plug this value into your equation for the pendulum's period to find out what happens.
