What is the purpose of the simple pendulum experiment?

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.

What is the conclusion of a simple pendulum experiment?

The surprising conclusion – the pendulum traverses a longer distance in a shorter time, than in a shorter distance, and its period is shorter. There are a number of reasons why Galileo thought that the period remains constant. One factor which Galileo failed to consider is friction.

What is the hypothesis of the pendulum experiment?

The hypothesis in this case would be, “changing the amount of weight at the end of the pendulum will change the period of the pendulum.” The experiment design would involve measuring the period with one amount of weight, changing the weight without changing any other variables, then measuring the period with the new …

What are the assumptions made in a simple pendulum experiment?

The pendulum string is massless. The pendulum bob behaves like a mass point. The system is frictionless. The potential energy of the pendulum is taken to be zero when the pendulum is at its equilibrium point, which is located at the bottom of the pendulum’s swing.

How can an experiment improve a pendulum?

Improve the accuracy of a measurement of periodic time by:

1. making timings by sighting the bob past a fixed reference point (called a fiducial point )
2. sighting the bob as it moves fastest past a reference point. The pendulum swings fastest at its lowest point and slowest at the top of each swing.

What is the aim of simple harmonic motion experiment?

Objective. The objective of this lab is to understand the behavior of objects in simple harmonic motion by determining the spring constant of a spring-mass system and a simple pendulum.

How can you improve simple pendulum experiment?

How do you conduct a pendulum experiment?

An example pendulum experimental setup.

1. Measure the period of your pendulum. Pull the weight of the pendulum back about 30 degrees.
2. Repeat steps 1–2 for your other pendulum lengths. Record all your results in your data table.
3. For each pendulum length, calculate an average period.
4. Analyze your data.

What is the differential equation of linear SHM?

The differential equation for linear SHM of a particle of mass 2g is d2xdt2+16x=0.

What effect does the mass of the ball have on the period of a simple pendulum?

The period of a pendulum does not depend on the mass of the ball, but only on the length of the string. Two pendula with different masses but the same length will have the same period. Two pendula with different lengths will different periods; the pendulum with the longer string will have the longer period.

How do you plot a simple pendulum graph?

Plot a graph between l (column, 2b) and T2 (column 5) by taking Z along X- axis and T2 along Y-axis. The graph comes to be a straight line. From this graph, for T2 = 4, l comes to be 100 cm. Hence for seconds pendulum (T = 2 s) length comes to be 100 cm.

What is the formula for simple pendulum?

Find here the period of oscillation equation for calculating the time period of a simple pendulum. The period of a pendulum formula is defined as T = 2 x π √(L/g), where T is the period, L is the length and g is the Acceleration of gravity.

What would be the method for pendulum experiment?

Initial Setting Up the Pendulum Experiment The pencil should be firmly taped to the top of the tabled, leaving about 4cm hanging over the edge. Next make a loop in your string to fit on the end of the pencil but do not make it too tight fitting. At the other end of your string tie your hook and slide one of the nuts onto the hook.

What are the disadvantages of simple pendulum?

The disadvantage of simple pendulum jaw crusher: Swing jaw has idle stroke, low production efficiency. The bottom horizontal stroke is large than that of upper, which does not match the crushing process.

What is the difference between simple and physical pendulum?

Torsional pendulum is actually a physical pendulum while a simple pendulum is actually ideal pendulum. The actual difference will be that in basic pendulum Center of mass and also centre of oscillation are usually at the exact same distance.
