Where H=vertical height of block inside liquid in equilibrium condition. Oscillation of block in liquid is another example of simple harmonic motion whose time period is given by When liquid placed in U-shaped tube is oscillated with the help of restoring force, the liquid inside each tube rises along the wall of tube which is simple periodic potion. This process of periodic motion of body inside earth hole is simple harmonic motion which is a theoretical example of SHM. This is because center of gravity pulls body back to it’s center and when it is pulled at center, gravity is zero which in tern makes the body to fall again. Then it will never fall on other side of the earth’s hole. When a hole is drilled through center of earth and a body is released inside it. Motion of body in hole drilled through center of earth Due to this harmonic motion, cradle moves to and fro for long duration even in single push. The to and fro motion of cradle is good examples of SHM. The motion of swing placed in parks, fair etc. Examples of such motion are to and fro motion of pendulum, viberations of a tuning fork, mass attached to a spring and many more. In both cases when mass is loaded and released, spring oscillates to and fro along with loaded mass which is an example of SHM. poor, so the car really oscillates up and down.
One is series combination of springs and other is parallel combination of springs. Simple harmonic motion (SHM) a special case of a periodic motion when the displacement x of. There are 2-cases on which the mass can be loaded on springs. When sound wave travels from outer environment to inner ear, the amplitude of wave vibrates eardrum in harmonic motion and perception of sound is recognized.
The process of hearing is of great importance in animal. The bungee cord when released oscillates to and fro & up and down which is of great entertaining purpose in our daily life. This type of pendulum is used in time keeping device like mechanical wrist watch.īungee jump is an example of SHM.
Torsion pendulum shows angular simple harmonic motion. The pendulum oscillating back and forth from the mean position is an. Thus, by application of SHM, pendulum clock are made which has great advantages in our daily life. The simple harmonic motion can also be taken as the projection of a circular motion with a constant angular velocity. Swings that we see in the park is an example of simple harmonic motion. This type of motion performed by pendulum is simple harmonic motion. This swinging mass also called as pendulum, moves to and fro motion. Pendulum clock shows time on the basis of swinging mass that is hanging below the clock. Motion of body in hole drilled through center of earth.10 examples of simple harmonic motion are listed as: There are so many examples of simple harmonic motion that are playing great role in our daily life as well as making our daily life activities easier. By understanding these phenomena, human being are able to make equipment, tools and machines that are boon for us. It is helping us in understanding different unknown phenomenon that are happening everyday in our own life.
Applications of science are making human beings more advanced.
