## What variables affect the period of a pendulum?

This can be explained by examining possible effects of each of the three variables: the length of the string, the mass of the bob, and the angle displaced. The length of the string affects the pendulum’s period such that the longer the length of the string, the longer the pendulum’s period.

## Does amplitude affect the period of a pendulum?

The greater the amplitude, or angle, the farther the pendulum falls; and therefore, the longer the period.) Since the force of gravity is less on the Moon, the pendulum would swing slower at the same length and angle and its frequency would be less.)

## How does changing the amplitude affect the period?

The period does not depend on the Amplitude. The more amplitude the more distance to cover but the faster it will cover the distance. The distance and speed will cancel each other out, so the period will remain the same.

## What are at least 3 different variables that could affect the period of a pendulum the time it takes to swing a full cycle )?

3 The three pendulum variables In this experiment, the period of the pendulum is the dependent variable. There are three independent variables: the pendulum mass, the amplitude of the swing, and the length of the pendulum string.

## How do you find the mass of a pendulum?

Section Summary

- A mass m suspended by a wire of length L is a simple pendulum and undergoes simple harmonic motion for amplitudes less than about 15º.
- The period of a simple pendulum is T=2π√Lg T = 2 π L g , where L is the length of the string and g is the acceleration due to gravity.

## How do you find the gravity of a pendulum?

Calculate the time of one oscillation or the period (T) by dividing the total time by the number of oscillations you counted. Use your calculated (T) along with the exact length of the pendulum (L) in the above formula to find “g.” This is your measured value for “g.”

## Can gravity change on Earth?

You are right – gravity does change across the surface of the Earth and throughout its atmosphere, due to several effects. First, there is the variation of gravity with latitude that you alluded to: you weigh about 0.5% more at the poles than on the equator. Second, gravity does indeed change with altitude.

## Why do lighter objects fall slower?

Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance. Air resistance causes the feather to fall more slowly.
