What instrument can be used to measure a circumference of a pendulum bob?
A flexible measuring tape can be used to measure the circumference of a pendulum bob. Wrap the measuring tape snugly around the pendulum bob to determine its circumference. Alternatively, a string can be used to measure the circumference and then measured against a fixed ruler or measuring tape.
How does the period of a pendulum difference theoretically with angular displacement and mass of ball for simple pendulum?
According to the mathematics and physics of the simple pendulum hung on a massless string, neither the mass of the bob nor the angular displacement at the limits of its swing has any influence on the pendulum's period.
Why does the length of the period increase as the length of the pendulum increases?
If this is a homework assignment, please consider trying to answer it yourself first, otherwise the value of the reinforcement of the lesson offered by the assignment will be lost on you.The period of a pendulum increases as it length increases because the verticle distance the bob travels is less, and thus there is less potential energy available to accelerate the bob in its arc. Also, recall that in vector mechanics the horizontal force vector due to gravity is a function of the direction the object is constrained to follow, and if the pendulum is longer, that direction is more horizontal, giving the horizontal force vector less of an effect.
Can perpetual motion be achieved using a pendulum in a vacuum?
Yes. In a vacuum, the only resistance is the friction in the suspension for the bob of the pendulum. Other than that, it should swing a long time. In air, friction with air will add to the friction in the suspension and it won't swing as well as it would in a vacuum. But it will swing for a while. A pendulum will swing in water, but the hydrodynamic drag will make it stop in a really, really short period of time. Just a couple of swings will strip the pendulum of almost all its energy. And the speed of the pendulum will be slower than in air, and it won't swing anywhere nearly as far through the bottom of its arc as it did in air.
The time period of a bob completely filled with mercury is T What will be the time period if the half of the mercury is removed from the bob?
We don't know anything about what the bob is hung with. Is it a bamboo pole ? A steel rod ? A chain or 1/4" aluminum cable ? Is it a thin massless thread ? It makes a difference, because the arc-period of the whole assembly depends on the length between its center of mass and the pivot. Since we don't know anything about the support, we'll assume it to be massless. Also, since we don't know anything about the bob itself, we'll assume it to be a point, with no dimensions, hanging on the end of a massless string. Now the period depends only on the length of the string, and is the same regardless of the mass or weight of the bob. So, removing half of the mercury from the bob has no effect on the period.
If the mass of bob of a simple pendulum is doubled its time period is what?
The time period of a simple pendulum is not affected by the mass of the bob, as long as the amplitude of the swing remains small. So, doubling the mass of the bob will not change the time period of the pendulum.
What is a pendulum bob?
The bob is the weight on the end of the pendulum.
The weight on a pendulum is called?
The weight on a pendulum is a 'mass' or a 'bob'.
WHAT IS the term for the mass at the end of a pendulum?
The mass at the end of the pendulum is the bob
What is the bob of a pendulum?
The bob of a pendulum is the mass or weight located at the bottom end of the pendulum that swings back and forth. It helps determine the period of the pendulum's motion and influences its overall behavior.
Does the period of simple pendulum depend on the mass of the bob?
Not in the theoretical world, in the practical world: just a very little. The period is determined primarily by the length of the pendulum. If the rod is not a very small fraction of the mass of the bob then the mass center of the rod will have to be taken into account when calculating the "length" of the pendulum.
What happens to time period of a simple pendulum if a heavy body is attached to it instead of bob?
The period of a simple pendulum is independent of the mass of the bob. Keep in mind that the size of the bob does affect the length of the pendulum.
What happen to the time period of pendulum if the mass of bob is changed?
The period of a pendulum is not affected by the mass of the bob. The period is determined by the length of the pendulum and the acceleration due to gravity. Changing the mass of the bob will not alter the time period of the pendulum's swing.
What does a Ellicott Pendulum measure?
An Ellicott pendulum is a temperature compensated clock pendulum. The metal rod of a pendulum changes its length with temperature. The consequence is, that a colder pendulum swings faster (the rod is shorter) and a warm pendulum swings slower (longer rod). The Ellicott pendulum compensates this temperature error of the pendulum. It consists of a steele rod and two brass rods, wich are connectet in one point above the pendulum bob. Brass has a higher temperature coefficient than steele. On the free end of the three rods, a special lever mechanism, controlled by the lenght difference of the rods, lifts the pendulum bob up, when the length of the rods grows. The bob stays at its position and the period of the pendulum is without temperature influence. See also http://commons.wikimedia.org/wiki/File:Ellicott_pendulum.png
What is the potential energy of a pendulum bob when it has a maximum kinetic energy?
When a pendulum bob has a maximum kinetic energy, all of the potential energy has been converted to kinetic energy. Therefore, the potential energy of the pendulum bob is zero at that point.
What is meant by bob in physics?
I THINK BOB REFERS TO THE BALL IN THE PENDULUM
What does a pendulum bob look like?
A bob is the weight on the end of a pendulum. It can take any shape, but is most often depicted as being round.
