It does, man ears are not able to hear such frequencies.
Yes, a simple pendulum can still vibrate in a vacuum because its motion depends on the force of gravity and its initial displacement. The absence of air resistance in a vacuum does not affect the pendulum's ability to swing back and forth.
A simple pendulum exhibits simple harmonic motion
Compound pendulum is a physical pendulum whereas a simple pendulum is ideal pendulum. The difference is that in simple pendulum centre of mass and centre of oscillation are at the same distance.
A compound pendulum is called an equivalent simple pendulum because its motion can be approximated as that of a simple pendulum with the same period. This simplification allows for easier analysis and calculation of its behavior.
A simple pendulum will not swing when it's aboard a satellite in orbit. While in orbit, the satellite and everything in it are falling, which produces a state of apparent zero gravity, and pendula don't swing without gravity.
A simple pendulum has one piece that swings. A complex pendulum has at least two swinging parts, attached end to end. A simple pendulum is extremely predictable, while a complex pendulum is virtually impossible to accurately predict.
applications of simple pendulum
The simple pendulum can be used to determine the acceleration due to gravity.
A simple pendulum.
Compound pendulum is a physical pendulum whereas a simple pendulum is ideal pendulum. The difference is that in simple pendulum centre of mass and centre of oscillation are at the same distance.
simple pendulum center of mass and center of oscillation are at the same distance.coupled pendulum is having two bobs attached with a spring.
The motion of the simple pendulum will be in simple harmonic if it is in oscillation.
