What is the conclusion on the experiment of a simple pendulum?

What is the conclusion on the experiment of a simple pendulum?

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?

We predicted that the pendulum with the shorter string would have the slower period. But the pendulum with the longer string had the slower period. Our results supported our hypothesis. The pendulum with the longer string had the slower period.

What is the purpose of the pendulum lab?

The purpose of this lab is to prove mass has no affect on the period of a pendulum only the length of the pendulum affects the period of the pendulum.

What are the sources of error in a simple pendulum experiment?

The possible sources of errors come from errors in measuring the period T using a stopwatch and errors in measuring the precise length of the string using a ruler or a meter stick. The surrounding air resists the rate of swinging of the pendulum and causes errors in the value of the period.

How do you measure the period of a pendulum more accurately?

My physics textbook states that in measuring the time period of a pendulum it is advised to measure the time between consecutive passage though the mean position in the same direction. This results in better accuracy than measuring time between consecutive passage through an extreme position.

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 bob in a pendulum?

A bob is the mass on the end of a pendulum found most commonly, but not exclusively, in pendulum clocks.

What factors affect the period of a pendulum?

The mass and angle are the only factors that affect the period of a pendulum. b. The mass, the angle and the length are the three variables affecting the period.

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.

Does the diameter of a Bob affect the pendulum?

The size (diameter) can affect the rate because increasing the diameter can shift the center of gravity of the pendulum. Whether that is an increase or decrease depends on whether the pendulum bob is supported from the bottom as with adjustable bobs, or hung with a fixed loop at the top as in some mantel clocks.

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 is the Bob of a pendulum?

A “bob” or “simple” pendulum is a pendulum consisting of a single spherical (or point) mass attached to a wire of negligible weight. A “physical” pendulum has extended size and is a generalization of the bob pendulum. An example would be a bar rotating around a fixed axle.
