How much does a pendulum weigh?
A pendulum is a weight suspended from a pivot so it can swing freely. The period of swing of a simple pendulum depends on its length (how far the mass is from the pivot) and is is independent of the mass of the weight. This means that you do not need to worry about the weight except to say that it must be heavy enough not to be disturbed by air currents.
What are the uses of simple pendulum?
Actually the simple pendulum isn't used much any more. But in earlier times the periodicity of the pendulum was used to drive the gears of mechanical clock; like the old grandfather clock that stood in the home of the rich back in the 1800s. Because the period of a pendulum was fairly stable and constant, it made an excellent source of energy for clockworks. But now clocks are driven by much more precise means, like crystals and atomic disintegration. And this is true in general; pendulums have been replaced by more precise means of providing periodic energy.
What is term declaration in physics?
Quite simple if you understand acceleration. Acceleration is the rate of change of velocity with time, which in simple terms means speeding up. The faster you speed up, the greater your acceleration. Deceleration is negative accelration, ie slowing down. Mathematically, acceleration = (final velocity - initial velocity) / (final time - initial time) and deceleration is acceleration with a minus sign at the start.
Is it possible for a body to have an acceleration when moving with constant velocity?
No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.
Does the mass of the pendulum bob affect the value of acceleration of gravity?
No, it does not. The earth's acceleration is relatively constant at or near the surface; about 9.8 meters per second squared. In short, just because the mass of an object is more or less does not mean it can affect the gravitational force of the earth. ================================= I think you may be asking whether the mass of the pendulum bob affects the result of the MEASUREMENT when we use that pendulum to measure the local acceleration of gravity. There again, the answer is No ... When you look at the formula that relates the period of the pendulum, its length, and the local gravity, the mass of the pendulum doesn't appear in the formula, and the result of the calculation is the same no matter how heavy your bob is. Now, if you want to get technical about it, the 'length' of the pendulum is the distance from the pivot to the center of mass. So, if the string or other means of suspension from which the bob hangs is NOT massless, then the mass of the bob does affect the position of the center of mass, and therefore the period of the pendulum. So for accurate measurement, it's always best to use the lightest possible string, and the most massive possible bob, in order to have the center of mass actually located as close as possible to where you THINK it is.
To determine the value of g acceleration due to gravity by means of a compound pendulum?
you can also use a simple pendulum to do it. your brain is full of problems if you cant do it by the easier wayForget thatgo on to this site and it gives you a method/procedure also go through www.phy.iitkgp.ernet.in/1styr/11-compound-pendulum.pdf
Does a pendulum undergo simple harmonic motion?
A simple pendulum undergoes simple harmonic motion only for small amplitudes because for small amplitudes the motion almost reduces to a straight line motion. Simple harmonic motion means motion on a straight not on curves
To determine the value of g acceleration due to gravity by means of an angular pendulum?
The period (time) of one swing of a pendulum is(2 pi) times the square root of (pendulum length / acceleration of gravity). There are three variables in this formula ... the length of the pendulum, the period of itsswing, and the acceleration of gravity. If you know any two of them, you can calculate thethird one. You want to use this method to measure gravity ? Fine ! Massage the formulaaround to this form Acceleration of gravity = (length of the pendulum) times (2 pi/period)2 then start measuring and swinging.The more accurately you can measure the length of your pendulum, from the pivotto the center of mass of everything that swings, and the period of its swing, and themore completely you can isolate everything from outside influences, like air currents,the more accurately you can calculate the acceleration of gravity, in the exact place whereyou run the experiment.

How you can use a simple pendulum to measure the pulse rate?
Pulse and pendulum According to his first biographer Viviani, Galileo experimented with synchronizing two clocks -- the human pulse, and a pendulum -- in his student days at Pisa. The resulting invention, the "pulsilogium", represented the pulse rate as the length of the pendulum. Try making a pulsilogium: adjust the length of a pendulum so that its rate of swinging agrees with your own pulse. Mark the length. Then adjust the same pendulum for your lab partner's pulse -- is there a detectable difference in pulse rate? 2. Pendulum length and frequency It would be good to know what pendulum length means as a frequency (or pulse rate). http://www.mtholyoke.edu/courses/mpeterso/galileo/time2.htm
What does acceleration is uniform mean?
It means that the acceleration does not change.
Will acceleration only speed up an object?
