- investigating factors that affect the swinging of a pendulum aim our aim is to find out whether changing the variables of the swinging pendulum affects the speed preliminary work in order to find out which variable/s affect the swinging of a pendulum, i need to test all the variables available. But if the red bob takes longer to reach the centre than the green bob that must mean its period is longer ie its angular frequency is lower and that's why damping increases the period of the oscillation. Regardless of lenght or swing of the pendulum its time is always the same this is referrerd to as the pendulums periodic swing as discovered by gallileo. Re: period and frequency of a pendulum doesn't depend on mass the swept angle does affect the time, but not by much until the angle gets large wiki article with formulas. Ing of a pendulum, which will keep the correct time the calibration affects the experimental results due to the direct correlation made between distance in the.
This physics video tutorial discusses the simple harmonic motion of a pendulum it provides the equations that you need to calculate the period, frequency, and length of a pendulum on earth, the. There are only two factors that affect the frequency of a traditional pendulum, the gravitational field strength and the length in an idealized world the bob is spherical and has a uniform distribution of mass. A pendulum is a simple device composed of a weight suspended on a string, wire, metal or other material that swings back and forth pendulums have been used in grandfather clocks and the like to keep time scientific principles govern what affects the swing rate of the pendulum these principles predict how a pendulum behaves based upon its features.
The independent variable of a pendulum by mahi chitti, jasdeep mundra, emily vu, and matthew berry purpose: to determine the independent variable that affects the period of a p endulum. What is the frequency of a pendulum that completes 45 cycles in 60 seconds 45 cycles/ 60 seconds what is the period for a pendulum that completes 2 cycles in 10 seconds. To keep things simple, in our derivation of the pendulum's acceleration, we assumed that the length of the pendulum's arm is 1 in fact, the length of the pendulum's arm affects the acceleration greatly: the longer the arm, the slower the acceleration.
-spaceship to test your pendulum on different planets (just kidding) in this activity you'll figure out how the pendulum's frequency depends on the length of the string, the weight of the bob, and the force of gravity. In this video david explains how a pendulum can be treated as a simple harmonic oscillator, and then explains what affects, as well as what does not affect, the period of a pendulum. For small oscillations the simple pendulum has linear behavior meaning that its equation of motion can be characterized by a linear equation (no squared terms or sine or cosine terms), but for larger oscillations the it becomes very non-linear with a sine term in the equation of motion.
I would say the effect of mass on simple harmonic motion that it will execute under given conditions depends on the nature of the restoring force and the final characteristic frequency depends on the ration k/m or restoring force constant/ mass. So the pendulum was the first oscillator of real technological importance in fact, though, the pendulum is not quite a simple harmonic oscillator: the period does depend on the amplitude, but provided the angular amplitude is kept small, this is a small effect. Construct a pendulum using the 30cm string and a washer attach it to a pencil and tape that pencil to the surface of the desk so that it swings freely this controlled-falling system is a weight (bob) suspended by a string from a fixed point so that it can swing freely under the influence of gravity.
The pendulum with the smallest period will have the highest frequency of vibration a longer pendulum has a higher period a shorter pendulum will have a smaller period thus, the pendulum with the shorter string will have a higher frequency of vibration. Period, t, is the time taken for one complete oscillation the period t of a pendulum is affected by the following factors 1) the length of the pendulum: - the longer the length, the longer the period (ie swing slower) 2) the gravitational field strength, g - the greater the g, the shorter the period. The length of the pendulum is directly correlated to its period as per the pendulum equation: t = 2π√(l/g), where t is the period of the pendulum, l is its length, and g is the gravitational constant 98 m/s 2 regardless of the weight of the pendulum bob, otherwise known as the weight at the end. A pendulum is a weight suspended from a pivot so that it can swing freely when a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position.
Ding 2 i will be investigating the effect of the length of a pendulum's string on the time for the period of that pendulum given my previous knowledge, i know that a pendulum behaves in an. It appears that the distance the pendulum travels back and forth does not affect how long it takes to complete a full swing you came to this conclusion and so did galileo. The lab report also should have the answers to the following questions the values of i lab report - obtain the frequency of the simple pendulum and to analyze the effect of change in amplitude, length and mass on the frequency.
