What is the reason of timing more than one oscillation?
To find the time period, the time for the number of oscillations more than 1 is noted because the least count of stopwatch is either 1 s or 0.5 s. It cannot record the time period in fractions such as 1.2 or 1.4 and so on.
Why do we use 20 oscillations instead of just one to find the period T?
The uncertainty is given by half of the smallest division of the ruler that we used. In order to minimize the uncertainty in the period, we measured the time for the pendulum to make 20 oscillations, and divided that time by 20.
How many oscillations would you need to be able to measure the gravitational difference?
To measure T, measure the time for 25 or 50 oscillations (swings) and then divide that time by 25 or 50.
What would be the most accurate way of measuring time for one oscillation?
A simple way to measure the pendulum’s period fairly precisely is to start the pendulum swinging, and measure the time required for a large number of FULL swings – 40, 50, or so. Choose the number of swings so that the total time for the measurement is 40 seconds or more.
How does length affect oscillation?
The longer the length of string, the farther the pendulum falls; and therefore, the longer the period, or back and forth swing of the pendulum. The greater the amplitude, or angle, the farther the pendulum falls; and therefore, the longer the period.)
What is the periodic time T of an oscillation of 50 cycles per second?
Low frequencies, such as 50 and 60 cycles per second (hertz), are used for domestic and commercial power, but… …be repeated is called the period T, given by T = 2π/ω. In Figure 22, the pattern is repeated every 16.7 milliseconds, which is the period.
When we measure the time period of a simple pendulum by noting 20 oscillations?
to complete 20 oscillations, what is the time period of the pendulum? Hint: Time period of a pendulum is time taken by it to complete 1 oscillation. Hence, the time period of the pendulum is 1.6 seconds.
What was the average time period of the pendulum for 20 oscillations?
Given: – 20 oscillations taking 32s to complete. Therefore 1.6s is the time period of the pendulum.
What is oscillation time?
The time for one oscillation is the period T. The number of oscillations per unit time is the frequency f. These quantities are related by f=1T f = 1 T .
Does the length of the string determine the oscillations in a given period of time?
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. This also affects the frequency of the pendulum, which is the rate at which the pendulum swings back and forth.
