What is the aim of simple pendulum experiment?

Spread the love

The goal of this experiment was to determine the effect of mass and length on the period of oscillation of a simple pendulum. Using a photogate to measure the period, we varied the pendulum mass for a fixed length, and varied the pendulum length for a fixed mass.

How do you do simple pendulum experiments Class 11?

Mark a point A on the table (use a chalk) just below the position of bob at rest and draw a straight line BC of 10 cm having a point A at its centre. Over this line bob will oscillate. Find the least count and the zero error of the stop clock/watch. Bring its hands at zero position.

What is simple pendulum in physics class 11?

A simple pendulum can be described as a device where its point mass is attached to a light inextensible string and suspended from a fixed support. The vertical line passing through the fixed support is the mean position of a simple pendulum.

What is practical simple pendulum?

A practical simple pendulum is defined as a small heavy sphere (bob), suspended by a light and inextensible string from a rigid support. Concept: Some Systems Executing Simple Harmonic Motion.

How do you calculate practical simple pendulum?

What is the conclusion of simple pendulum experiment?

Answer: The surprising conclusion – the pendulum traverses a longer distance in a shorter time, than in a shorter distance, and its period is shorter. … This friction slowed down the pendulum’s faster movements and led to a decrease in the length of the arc through which it passed.

What is simple pendulum with diagram?

A simple pendulum has a heavy point mass (known as bob) suspended from a rigid support by a massless and inextensible string. When the bob from its mean position is pulled to one side and then released, the pendulum is set to motion and the bob moves alternately on either side of its mean position.

What is the law of simple pendulum?

According to the laws of simple pendulum. A simple pendulum’s period is directly proportional to the square root of its length. A simple pendulum’s period is inversely related to the square root of gravity’s acceleration. A simple pendulum’s period is independent of its mass.

Which type of motion is simple pendulum?

The simple pendulum is another mechanical system that moves in an oscillatory motion.

Why simple pendulum is called simple?

The simple pendulum (see wikipedia or hyperphysics) leads to a simple differential equation by using Newton’s second law: ¨θ+glsin(θ)=0. This pendulum gives the easiest way te look at harmonic motion. The above case is what they call the simple pendulum.

What is the difference between practical and ideal pendulum?

A simple pendulum is an idealized version. It’s not real. The stick is massless, and the bob is a point mass. A compound pendulum is a real pendulum with a real stick with real mass and the bob had moment of inertia as well as mass.

What is the time period of simple pendulum?

Period (T) of a simple pendulum is T=2π√L/g. A simple pendulum consists of a mass (m) hanging from a string of length (L) and fixed at a pivot point (P).

What is the result of simple pendulum?

T=2π√mk=2π√mmg/L. for the period of a simple pendulum. This result is interesting because of its simplicity. The only things that affect the period of a simple pendulum are its length and the acceleration due to gravity.

How do I calculate g?

G is the universal gravitational constant, G = 6.674 x 10-11 m3 kg-1 s-2. M is the mass of the body measured using kg. R is the mass body radius measured by m. g is the acceleration due to the gravity determined by m/s2.

What is g in pendulum equation?

L = length of the pendulum. g = acceleration due to gravity. This worked example problem will show how to manipulate this equation and use the period and length of a simple pendulum to calculate the acceleration due to gravity.

What is the procedure of pendulum experiment?

  1. Take your string back about 40 – 50 cm.
  2. As you let it go, start the stop-watch, and count the number of oscillations in one minute.
  3. Repeat the experiment 5 times and calculate an average.
  4. Put another weight on the hook.
  5. Release the weight from exactly the same place.

How do you find the gravity of a pendulum?

Measure the time period T for one oscillation using a stopwatch. Determine the length L of the pendulum. Divide the length L by the square of the time period T . Multiply the value obtained from Step 3 by 4π² and you will get the value for acceleration due to gravity, g .

How is a pendulum set?

Oscillations (to and fro motion) are set up in a pendulum by displacing the bob from its equilibrium positions and releasing it. The period of the pendulum is the time required for the pendulum bob to complete one oscillation (cycle).

What is the introduction of simple pendulum?

Introduction. A simple pendulum consists of a small bob of mass (m) suspended by a light (assumed to be massless) string of length (L), and the string is firmly attached at its upper end. This pendulum is a mechanical system which we will assume exhibits simple harmonic motion.

What affects the period of a pendulum?

The only factor that significantly affects the swing of a pendulum on Earth is the length of its string. Students might wonder why the length of the string is the only thing that affects a pendulum’s period.

What is the dependent variable in a pendulum experiment?

Dependent variable: The dependent variable is the time period for one oscillation. Constant/ Control measures: The constants considered in this experiment are: The mass, shape, size and diameter of the bob The amplitude (angle) at which the spring is gently left to oscillate.

Why pendulum is used in clock?

pendulum, body suspended from a fixed point so that it can swing back and forth under the influence of gravity. Pendulums are used to regulate the movement of clocks because the interval of time for each complete oscillation, called the period, is constant.

What is amplitude of a pendulum?

Amplitude. The amplitude is the maximum displacement of the bob from its equilibrium position. When the pendulum is at rest, not swinging, it hangs straight down.

What time period is SHM?

Time Period and Frequency of SHM The minimum time after which the particle keeps on repeating its motion is known as the time period (or) the shortest time taken to complete one oscillation is also defined as the time period. T = 2π/ω Frequency: The number of oscillations per second is defined as the frequency.

What is the length of the pendulum?

Pendulum clocks should be attached firmly to a sturdy wall. The most common pendulum length in quality clocks, which is always used in grandfather clocks, is the seconds pendulum, about 1 metre (39 inches) long. In mantel clocks, half-second pendulums, 25 cm (9.8 in) long, or shorter, are used.
