Question

define the following terms
a)simple pendulum
b) length of pendulum
c) oscillation
d)time period​

Answer 1

Answer:

1. A simple pendulum consists of a mass m hanging from a string of length L and fixed at a pivot point P. When displaced to an initial angle and released, the pendulum will swing back and forth with periodic motion.
2. 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
3. One oscillation of a simple pendulum is one complete cycle of swinging one way and then returning to its original starting position
4. time taken for one complete cycle of vibration to pass a given point. As the frequency of a wave increases, the time period of the wave decreases. The unit for time period is 'seconds'

Answer 2

Answer:

a) an ideal pendulum consisting of a point mass suspended by a weightless inextensible perfectly flexible thread and free to vibrate without friction —distinguished from physical pendulum.

b)The length of the strings from the point of suspension to the center of the bob is called the length of the pendulum. oscillation of the pendulum = One complete to-and -fro motion of the bob about its mean position.

c)Oscillation, in general, is a periodic fluctuation between two things; in the broadest sense, oscillation can occur in anything from a person's decision-making process to tides and the pendulum of a clock. ... In a pendulum-driven clock, for example, the oscillation is the back and forth movement of the pendulum.

d) A time period (denoted by 'T' ) is the time taken for one complete cycle of vibration to pass a given point. As the frequency of a wave increases, the time period of the wave decreases. ... The period of a pendulum is the time it takes from one side to the other and back.
