Why are motions that are exactly simple harmonic rare?
Answer and Explanation: Simple harmonic motion is rare because in nature the frictional forces are not negligible and bodies that move in an oscillatory manner decrease their amplitude in their interaction with the air that surrounds them. Simple harmonic movement is characterized by having a constant amplitude.
How simple harmonic motion is related with our daily life working experience?
2. Swing. Swings in the parks are also the example of simple harmonic motion. The back and forth, repetitive movements of the swing against the restoring force is the simple harmonic motion.
How is periodic motion related to real life?
Periodic motion is performed, for example, by a rocking chair, a bouncing ball, a vibrating tuning fork, a swing in motion, the Earth in its orbit around the Sun, and a water wave.
Why is SHM important?
Why is simple harmonic motion so important? Simple harmonic motion is a very important type of periodic oscillation where the acceleration (α) is proportional to the displacement (x) from equilibrium, in the direction of the equilibrium position.
Is SHM a hard topic?
Some will find Simple Harmonic Motion (SHM) as a tough topic while others may struggle with Electricity and Magnetism. So, there are few things you can do which will help you all along in the course. They are as follows: Make a short note of all relevant facts and formulas of the given topic.

What is the minimum rank to get into NIT?
Usually, a rank greater than 70,000 can be considered as the low JEE Main Rank, and students are often confused with regard to the admission chances in NITs. If you are aspiring for top NITs, your rank should be less than 10,000. However, newer NITs accept candidates with a rank greater than 70,000 in JEE Main.
