What is the effect of mass on number of swings in pendulum experiment?
While we consider the pendulum experiment, we consider so many assumptions that the string is inelastic and there is no air friction to the movement of the bob. With all these, we derive the expression for the time period of the pendulum as T = 2 pi sqrt (l/g) Here, in no way, mass of the bob comes to the scene. So, mass of the bob does not have any effect on the time period or its reciprocal value, namely, frequency. ie number of swings in one second.
Where does the bob have the highest potential energy?
-- If you're talking about a pendulum, then the potential energy is highest and kinetic energy is zero at the ends of the swing, and potential energy is lowest and kinetic energy is highest in the middle of the swing. -- If you're not talking about a pendulum, then the preceding may be completely wrong.
What are the basic condition for the system to be called simple pendulum.?
what is the principle behind simple pendulum no because heavy body is suspended with light extensibe string.
How does gravity affect a pendulum?
Very little affect. The weight is chosen by: 1) Won't require enormous bearings, or clockworks. 2) Heavy enough so that air resistance is not the dominant force. 3) Not so heavy that the Earth's rotation will not break the clock. etc.
Why does a swinging pendulum lose energy once it is set into motion?
When a pendulum is released to fall, it changes from Potential energy to Kinetic Energy of a moving object. However, due to friction (ie: air resistance, and the pivot point) and gravity the pendulum's swing will slowly die down. A pendulum gets its kinetic energy from gravity on its fall its equilibrium position which is the lowest point to the ground it can fall, however, even in perfect conditions (a condition with no friction) it can never achieve a swing (amplitude) greater than or equal to its previous swing. Every swing that the pendulum makes, it gradually looses energy or else it would continue to swing for eternity without stopping. Extra: Using special metals that react little to temperature, finding a near mass-less rod to swing the bob (the weight) and placing the pendulum in a vacuum has yielded some very long lasting pendulums. While the pendulum will lose energy with every swing, under good conditions the amount of energy that the pendulum loses can be kept relatively small. Some of the best pendulum clocks can swing well over a million times.
What is the bob of a pendulum?
The bob is the weight at the end of the pendulum. For example, in a grandfather clock the ball at the end of the stick is the bob.
The weight on a pendulum is called?
The weight on a pendulum is a 'mass' or a 'bob'.
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 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 meant by bob in physics?
I THINK BOB REFERS TO THE BALL IN THE PENDULUM
What are the parts of a pendulum?
There are three parts to a pendulum. The bearing, the bob, and the string or wire supportig it.
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.
Rosa's family has a grandfather clock with a pendulum The clock is not keeping time correctly because the pendulum is swinging too quickly What could Rosa do to slow down the pendulum swing?
To slow down a swinging clock pendulum, one must make it longer. In mechanical clocks, the majority of the mass of the pendulum is contained in the "bob" (a disk or weight) usually at the bottom of the pendulum. If you lower the pendulum bob, the pendulum is lengthened and the pendulum runs slower. This is usually done by turning a nut on a threaded portion of the pendulum just below the bob. Make sure the bob drops as you lower the nut or nothing will change. To raise the rate of the pendulum (make it run faster), you just turn the nut the opposite way.
How does a pendulum bob filled with sand and a hole at bottom affect the time period?
At the extremities of the pendulum's swing, the sand leaving the bob could exert a force on the bob. Provided that this force is negligible and also, provided the mass of the bob (with or without the sand) is large compared with the rest of the pendulum, the time period should not be affected.
What effect does decreasing the weight of the bob have on the period of the pendulum?
The weight of the bob will determine how long the pendulum swings before coming to rest in the absence of applied forces. The period, or time of 1 oscillation, is determined only by the length of the pendulum.
How does the bob affects the period of a pendulum?
The period of a pendulum is totally un-affected by the mass of the bob.The time period of pendulum is given by the eqn.T=2*PIE*(l/g)1/2 ;l is the length of pendulum;g is the acceleration due to gravity.'l' is the length from the centre of suspension to the centre of gravity the bob.ie.the length of the pendulum depends on the centre of gravity of the bob,and hence the distribution of mass of the bob.
What happen to the time period of pendulum if the mass of bob is changed?
If you make the simplifying assumption that everything except the bob is massless, then the mass of the bob has no effect on the period.
